Well that didn't go so well(clear coat)

[Guest]

It seems I didn't really make sure my Campbell Hausfeld spray gun was in tip top shape before spraying the clear;






Sags,runs and air bubbles everywhere.When I took the gun apart it seems the O ring on the front fixture was bad.the bit the O ring was on wasn't tight either.Before taking it apart I wasn't getting good atomization,afterwards it was looking MUCH better.

This sidecover did turn out nice.
Lesson to be learned.CHECK THE EQUIPMENT BEFORE YOU DO STUFF

Lesson to be learned, don't ever think of using crappy sprayguns.
Just ask Pete...


Sorry Greg

1000 grit wet by hand and than get a new sprayer.. it might fix it.

[nejeff]

Did you spray outside? Looks like you picked up some "debris" on some pieces.

"If you can't fix it, feature it!!"

It takes a special touch to get that much orange peel and to do it so evenly.

Crappy guns can work just fine.

[gearheadE30]

Might be salvagable with some wetsanding, except maybe for the air bubbles...

[rustybronco]

Crappy guns can work just fine.

Yes they can.. and 'can' is the key word. But more often than not, you need to work with and on them to get some semblance of a proper spray pattern. Plus they tend to be air hogs. Combine that with a small CFM compressor? boy, that 'could' be a recipe for disaster.

Man sand it down to colour
that is a shame after all that hard work.

I had to convert my garage to a mini cross draft spray booth to paint my buddies bike. We hung heavy canvas tarps. On the back side put 3 box fans with hepa filter material tapped to the backs and ran them on low. Had to wet down everything with the garden hose before any paint and a again before the clear. It was a lot of work but it was better than paying a paint shop top dollar to do it. From the experience in the auto body schooling that I went through for two years and the body shops that I have worked in I don't think wet sanding to smooth the clear out will do much if you war looking for a mirror finish. But consider even factory paint jobs today have a good amount of orange peel, its done that way so the base doesn't fade out as fast if at all.

OK it is not the best gun but it is better than this.

It's the same gun that shot this.I think I broke it down and didn't reassemble it right.We should all know how important good O rings are to.Don't forget I am a novice at this stuff.A new gun just ain't going to happen,why do you think I was asking about 2K can coverage http://www.thegsresources.com/_forum...d.php?t=209101 ?The way it was the gun was just throwing tons of clear at the pieces.Will be wet sanding it and re-clearing next weekend,most of what looked like bubbles are gone.It's just a temporary set back.

Hate to disagree with rusty, but I have done a fine job with a $15 HF gun. The trick is that the nozzle is very small iirc 0.7, so you go over so many times it will not run and I never recal it sputtering. Also key is a pressure regulator at the gun (I also have a gauge there) and make sure the is no water in the compressor.

I probably posted which gun. It is a hvlp touch up gun with purple handle.

Jim you can do a good job with a 'el cheepo IF it's working correctly, As I recall you had to hold the lid in place on your HF gun with rubber bands. Just think of all the work going down the drain if that lid came off or leaked when you were shooting clear on top of a fuel tank? Way too much work going down the drain to correct if that happened in my opinion.

Greg, No one ever said you need to buy a new gun. There are plenty of good used professional guns out there for sale for under $50 as there are good off brand ones for not much more. I paid somewhere around $68 for my Astro EVO when I bought it new. A person can buy a NEW Sharpe SFG-98 HVLP (an older model) on Ebay for under a hundred bucks which will do a fantastic job putting down paint. It uses a bit of air at 11 cfm or so, but even with a 1.5 tip powered by my old 1 hp twin cylinder compressor, it did a nice job on the Honda's body work if you let the compressor recover in between sessions.

As with most good guns, when you are done spraying, all you need to do is run some thinners through it, unscrew the air cap, scrub it and the nozzle, put it back together and it will be ready to shoot the next time. No worrying about leaky packing's, or a spray pattern that shoots lopsided. No spitting, dripping from the cup, or wondering if it's going to spray the same way as it did the last time you used it.

They don't have to be expensive, just good.

Don't forget I am a novice at this stuff.

I'm far from a being a professional myself.

Yep, I have used the same gun on six or seven bikes now. They are not perfect, but none of the flaws were the gun, they were me taping it poorly or a fly's leg getting in it or things like that. Overall it's great for the price.

Dale there are 2 used guns listed on UsedVic,one's a CH gun that might be better but I somehow doubt it. http://www.usedvictoria.com/classifi...y-Gun_19996057 other ones even more vague http://www.usedvictoria.com/classifi...tools_19995007 and missing stuff to Oppps found a third one http://www.usedvictoria.com/classifi...y-Gun_19779638 and $80 is pie in the sky now.Even set up badly pattern has never been my guns problem.
Just a note I drained the compressor tank and water separator.Being on the wet coast I needed to.
