    I'm with Dale on getting a decent gun. Paint is expensive, and it takes a lot of time to prep the parts for paint. Spending a few bucks on a nice gun is not asking that much when you consider what's involved.

    EDIT: Do NOT buy the POS Campbell Hausefeld gun. It's junk.

    EDIT 2: Water in the air tank is a REAL problem. I have two different water separators on my compressor and water still gets through. You need to knock down as much water as possible at the tank, AND use a small filter at the gun as well.

          Greg, if you choose to work with the gun you already have, good on you! There's nothing wrong with that if it works just fine. Someday, maybe, when the money allows, you may want to upgrade to something better. Who knows what the future will bring.

          Do what your pay check allows you... I do. Why do you think I'm rebuilding my trailer instead of buying a new one? I certainly isn't because I'm flush with cash.

            So I do have one question,how long should I wait before I sand this down?Really wish a better gun was an option but it just isn't.

              It all depends on how well the clear sets up. If it's hard enough to sand without gumming up the paper in a two or three days, and if it were me trying to save what I could rather than starting all over again, I'd make certain it's hard all the way through before trying to knock down the heavy stuff.

              You used a hardener in the clear didn't you?

              By the way, you'll need some thing a bit more aggressive than 1000 grit to sand those runs down at first. I'm thinking 320 used 'wet' on the heavy stuff, then you can work your way on up the grit scale when you get the high spots knocked down. It all depends on how much clear is over the base and how the defects look.

              Personally, I'd strip the tank and start over. Sorry..

              How about a few more pictures now that everything has had a chance to settle down a bit.

                If you used 320, then you will have to respray. If there are high spots then even an 800 will knock them down fast. If there is any hope of salvaging a finish shine, you will have to get back up to 1500 and 2000 before buffing.

                  I'm not saying mine is the best way nor the only way of doing things. It's all up to the person with the sanding block in his hand.

                    All depends on what it is. Check the data sheet that came with the paint and it shoud tell you how long the paint will take to be "dry to the touch" and "fully cured". If it is a catalyzed polyurethane you can start wet sanding it in as little as 24 hrs.

                    For the big runs and drips you can cut them down with a razor block or nib file to save time and excess sanding. Then go over it with 600 grit wet paper. For some of the thicker runs/sags you will have to use something a little coarser like 400 grit to cut them down. You'll have to go slow and do one small area at a time to avoid cutting into the color underneath. It will be tedious work but I think you can salvage it. When you get it all smoothed out to where you are satisfied with it, prep and reshoot the clear. Do one piece and make sure the clear is laying down and flowing out properly before moving on to the rest of the pieces. I'm sure that you don't want to have to sand everything out again if it isn't turning out right the second time.

                      OK I already have more clear so getting what I have here smooth enough to reclear is what I'm after.Yes Dale I put the recommended 4:1 hardener ratio in the clearcoat.Have some 400 wet/dry here to knock down the worst stuff.Will wait till Thursday to start that,just to be sure.Did do a gun improvement to:


                      A gauge/regulator at the gun,figure I can use it if there is a better gun in my future.

                        Also, I have found it well worth it to buy and use the silicone and detergent solvents to wipe the surfaces with, prior to spraying, followed by a tack cloth.
                        I may not have read every single word of the thread, but ... what paint system are you using?

                          I was using up some Nason clear I had left over from the time I painted the 85 750 yellow.It's going over Plasti-Kote and Dupli-Color automotive touch up paint that's been freshly applied.The supplier I use is dropping Nason and DuPont systems in favor of Valspar so the new clear I bought is Valspar.The Nason clear was 2 years old but Larry (NVR2OLD) told me to get new hardener so I did.Only repainting because I didn't put enough hardener in the clearcoat when I did it yellow

                            Bugger Greg! She was lookin' real purdy too...

                            I've got Supercheap auto guns, probably the equivalent to the HF guns for you guys I would guess.

                            They're ok, but that's about it... took a lot of effort and advice from Dale and others to get the pattern and flow right for a reasonable finish. The touch up gun also started falling apart the first time I used it

                            I just got my rear guard and tail light bracket re-sprayed by the guys who did the crash repair and I see the huge difference with quality equipment. It looks to be a much thicker finish, no orange peel, top job. I have no doubt their extra skills made a big difference too

                            When I eventually get my hands on a Katana it will be a restore/rebuild job (no $$$ for a mint one) and hopefully I can get my hands on an Iwata or something by then as I think it will make it much easier to get a good job done.

                              Pete, the image of red paint on you brick work from that gun coming apart is indelibly etched in my mind!

                              If you can find an Astro (star) EVO4014 in nice condition and on the cheep, you might want to give that a try instead of spending the money on an Iwata. I have both the LPH400LV and the EVO4014 and I can assure you it's no slouch when it comes to applying paint.

                              *** silicone and paint... bad juju... ***

                                Well this gun has not fallen apart so it's got to be a step better,right?Admittedly it's a very basic gun but I was VERY happy with the results first time out.I have not touched it in the 2 years since I used it last,not sure if getting a better gun is even worth it for the amount of spraying I do.Just one note to,where the clear is good the paint looks just fantastic,the red really pops and the black subtly sparkles in the sun.Some careful sanding and a reclear it should be good to go
