    Hi Guys

    this site isn't realy photo friendly to attachments, I guess I'll have to set up a photbucket account or simialr, but I will post of afew photos of my most recent projetcs, promise.

    Hi Pete

    I guess I wasn't really following the masking tape/material questions all that well. As I understand your posts you want to paint mainly red, with a couple of white stripes? Forget the butchers paper, aluminum foil, masking materials, etc

    the very easiest way to do that, and get fabulous results, is to simply paint all the parts white, let the white colour coat set up, use pro painters tape to lay down your stripes by taping off exactly where you want your stripes to be, then spray the entire part red however many coats, then while the red colour coats are still wet, peel the pro painters tape off at a bit of an angle exposing the white stripes, then clear everything.

    taking the pro painters tape off while the overcoat is still wet prevents any flaking or cracking of the paint, leaves a really clean crisp stripe line, and then the clear overcoat levels everything perfectly smooth.

    your local autobody paint supplier should set you up with the pro painters tape, some solid advice on the materials you are working with, and some proper cone paint filters as well as an inexpensive paint gun stand typicaly made of wire. Don't forget the "gun wash" to clean out the gun between white/red/clear.

    Once you have laid out the tape to mask the edges, hit the area to be painted with light coat of the color under the masked area. So for your project, assume that you are painting the white stripes first and then masking off the white stripes to lay down the red.

    Once you have papered and taped the white stripes, spray a light coat of white paint over the taped edge. Let it dry a bit, then proceed to paint the red.

    The initial coat of white is supposed to help seal off the masking tape, to reduce or eliminate bleed through. Basically, the white bleeds through and prevents the red from doing do.

    Good luck.
    Yeah this trick also works with clear.A light coat clear over the masking stopped the bleeding of the top colour.I was using rattle can lacquer so a slightly different process.Did it with my 81GS650E.Sadly I have no pics of that bikeThe light silver with a real dark blue was so nice.

    I'm pretty excited to see how you turn out here Pete.
    Also, I forget where, but I read you can use aluminum foil to mask off large areas.
    I've done a little painting and never once had it make the ink run on the foil, or had it soak through!

    are you sure this is a fuel resistant paint? why do I get the feeling it's acrylic lacquer not a ??-urethane? possibly because it says dura-lac?

    500 Series is a basecoat that must be finished with a 2-pack clear coat

    Pete, you can never go wrong with the manufacturers recommendations. if they say you can re-coat or top coat up to 24 hours, then you have at least 24 hours to tack it off and re-coat. read the Technical Data Sheets.

    Don't be drawn into laying the material on too heavily, several thinner coats are always better, learn to quit while you are still ahead......
    excellent advice!

    as long as it's dust free and the solvents don't cause the ink to run, I don't see an issue with it. I've painted many things using newsprint as masking paper in the past. just watch out for the dust...

    I use a nail driven into the end of my saw horse to hang my gun when not in use. if the distance between gun body and the trigger is wide enough I even 'hang' it on the back of a chair from time to time.

    If that will work, I already should have plenty in the garage with my newspaper stash

    Hey Paul

    I did a 1979 Laverda 1200 Mirage in orchid green, with prismatic flake in the first two coats of clear, then gold flake in the next two coats of clear, then 4 more coats of clear clear, then wet sanded and polished, the sucker is absolutely glass smooth and mirror shiny. I also did a 70's Kawasaki in fire engine red with silver flake, same result, better than most pro shops, and I am just a home hobbyist.

    Aaaah butchers paper! Good call, I'll try to track some down and yeah I only need a couple of metres really. That plastic would be good too although I think paper might be easier to work with. I figured 400M of masking paper was somewhat over kill

    it is important to let the final clear coat sit for at least two days before you start on wet sanding, it needs time to at least partialy set up but will still be "soft" enough to easily work after say 48 hours or so.

    if you haven't sprayed with your HVLP gun before, practice setting up the spray pattern and material volume, get the air pressure set up right, spray some test panels. The gun manufacturer will tell you how far away or how close to be from the material, the newer HVLP guns are sprayed close, say 8 inches or so. Always start your spray run off the piece and continue all the way through to off the other side wherever possible. Don't be drawn into laying the material on too heavily, several thinner coats are always better, learn to quit while you are still ahead......

    perfect surface prep and good adhesion are the basics, then the final wet sand and polish are the icing on the cake, the actual spraying is the least of the work. You can do better than many pro painters working from your own garage if you prep properly, and wet sand and polish at the end, your aspirations for something to look good from a meter away are far too low, you should see some of the paint jobs I have done from my home as a hobby, over this past summer I did a 1979 Laverda 1200 Mirage in orchid green, with prismatic flake in the first two coats of clear, then gold flake in the next two coats of clear, then 4 more coats of clear clear, then wet sanded and polished, the sucker is absolutely glass smooth and mirror shiny.

    Hmmmm see that makes sense too...

    There are tips in there as to distance from surface etc. so I'll be reading more thoroughly yet.

    Larry says he waits overnight before doing the next colour specifically to stop tape marks from the masking. The tape off time is 20 - 45 min's with this paint. So you think that's safe enough without leaving tape marks? As it is there'll only be the two stripes being masked for, not anything complicated.

    Then after the white, I'm assuming the tape time is also what I'd be best leaving before removing the tape and clearing. Make sense?

    My whole issue at the moment is a complete lack of self-confidence in doing a good job, but I will certainly be putting the prep. and follow up effort in to get the best results I can.

    Those paint jobs sound great! If I can achieve something like that then I will be even more than stoked

    Thanks again for these replies guys, I'm starting to get a grip in my head which is helping no end

    By that I mean the base colour goes on, 2 to 3 coats, 10 - 15 min's between coats for flash off, wait 45 min's 'til dry then mask of for the stripes, repeat for stripes, wait another 45 min's then I can start the clear coat?

    Is that right or should I leave the colour over night before doing the clear?

    Going by those times, in theory I could be done in about 5 hours or so...

    pretty much most colour paint is going to be "reduced" at whatever ratio. Reduce the entire btach at once for consistency. Reduced is not catalyzed, no chemical reaction as such, just a dilution, and stays good in the can for months..... Clear coat on the other hand is catalyzed, when you add in the activator you start the chemical reaction, which ultimately causes the stuff to turn hard, so don't catalyze a huge amount of clear at once, only do enough for at most a couple of coats, easy to catalyze more as needed.

    it is important to let the final clear coat sit for at least two days before you start on wet sanding, it needs time to at least partialy set up but will still be "soft" enough to easily work after say 48 hours or so.

    No, clean the gun when you are finished with each material used. not needed between coats unless you wait so long between coats that the paint starts to harden.

    mix enough paint for what you intend on using for the complete stage, not just for each coat. mix enough base for 2~3 coats... enough clear for 2 coats... ect.
    Haha I like your confidence Dale! Maybe some will rub off on me once I've started

    Cool, I thought it was a big task to be cleaning between coats... flash off time is 10 to 15 minutes so that was gonna be a huge rush to give it a quick clean, mix a new batch, and get ready to spray in that time frame...

    I really am thinking I'm getting my head around this finally, or at least I hope I am!

    So should I be looking for something more like this?



    I realise that's huge but is the first thing that popped up and I'll be trying to find something a little more appropriate to the size of the pieces...

    Edit: Found one a bit more appropriate and even has free postage, looks right does it?

    Yeah the prices here are insane! I could've got 4 litres from the mob I got my paint from for $130 yesterday but what would I have done with about 3 1/2 litres of 2K primer? Oh well I have it now

    I also found Ed's thread on his two tone paint and Larry posted on there that he leaves a day between colours, leaves the white until last, then clears straight after the white.

    That should actually work well for me as the bulk will be maroon, so I can do that and the black on the first day, then mask and do the white on the second day followed by clearning the lot.

    I think I'm starting to get some of this into my thick head at last...
