I cringe almost, every time when someone starts a thread looking for a recommendation or using "cheap" (primer, base, clear, gun, compressor,
ad infinitum) "Good" costs money, time and effort. My attitude is that if you can't do it right, why do it at all? The only exception is trying to learn yourself something. But even then having really good material/equipment let's you eliminate or minimize one set of variables.

novafreek6872 THANKS FOR THE NICE COMMENTS!! Decklid (top) and driver fender are next up, they are in epoxy primer waiting for a final wetsand then topcoat. Hopefully the 1.4 HF gun will give me a smoother finish than my "primer gun", in fact I'm sure it will, and I will have less work to do AFTER the paint dries.

After that I will tackle the hood and cowl panel, and finally the biggie: the back half of the unibody. The quarters will require a ton of priming, blocking, and maybe even some filling, they are the primary trouble area of the car. Lots of ripples.

I'm very happy with how its coming and every day is a new day, no need to dwell on the crappy things that happen from time to time.

Handfull54 Very nice. You should be proud of yourself. Shows what time and patience can do. Like I thought when painting my truck' "who is going to care more about this paint job than me?" Take a couple of bows. You earned it.

novafreek6872 took a few pics today outside. I'm happy with how its coming along. Also used purple gun #2 today to spray some epoxy on other parts (i took it apart and soaked it for 2 days in lacquer thinner before I ever used it and scraped all the silicone sealant out. Replaced with carefully applied teflon tape.) Happy to report that I had no fisheyes and it sprayed wonderfully. Cant wait to try it out with the topcoat. The dust you see in the 3rd pic is NOT in the paint. The parts sat out in the sun all afternoon and got a little dusty.

novafreek6872 Brian, YES, its definitely the gun, trust me! BEWARE: Buyers of cheapo HF PURPLE guns...THEY ARE LOADED WITH SILICONE CRAP!!! CLEAN GUN COMPLETELY BEFORE USING!!!!

MARTINSR Nova, is any of this "contamination" on vertical surfaces? All I saw it on was the horizontal surface of the door laying on it's back. If you see only contamination on the horizontal surfaces (stuff falling on it from the air) and none on the vertical surfaces, keep an open mind.

Handfull54 It's back to the old saying that applies to just about everything. " Buy cheap buy twice". Hope everything turns out OK. I wasted a gallon of paint which cost $400 because I bought a cheap compressor which could not keep up. Half the panels would be OK the other half was like suede all dry. So I bought a big compressor and problem solved. Just like most of us learn about trying to save a buck sometimes is not worth it.

novafreek6872 See my particular gun sprayed fine at first until the silicone they used on the threads of various parts started breaking down from chemicals in the paint I guess. That's where all the trouble started.

I'm really good at taking them apart now!! LOL. :-)
05-11-2012 10:18 AM
novafreek6872 Yep. Definitely the gun Barry. I should have got a pic of the inside. Right where the paint comes thru it was loaded up with gooey silicone. This is on of the cheapie HF purple guns BTW. Cost me a lot more than money! But I learned a valuable lesson. The hard way of course!!! I don't think ill ever trust a new gun again tho... at least a Chinese one.

I will be using my old faithful siphon gun this time that I used on the hood I painted about a month back, hasnt let me down yet and did a wonderful job spraying epoxy last night. HUGE fan.

Plus I bought a super deluxe gun cleaning kit at my local auto paint store to keep everything going smoothly on this project from here on out.

WORD TO THE WISE: IF YOU BUY A GUN TAKE IT APART AND FIND OUT WHATS IN IT BEFORE YOU TRY TO SPRAY TOPCOATS WITH IT!!! Cost me 2 days work plus materials wasted.

May be common knowledge round here, but I didnt know...

Andy, are you sure it is the gun? I buy 2-4 new guns a year as i use them everyday and I have never taken a gun apart before spraying with it, yes i do shoot a coffee cup full of urethane reducer through it first but that is it.

If gun was contaminated, I would guess by second or third panel the gun would be clean and start shooting with no problems. Just a guess on my part.

The tech line averages 6-8 calls like this a day and I can say this with a 100% accuracy, 99 times out of a 100, it is always vapors coming from the air line, with out question.
One time out of 100, it will be other contamination, from car, shop or person painting.

Just a thought that might save you some headaches.

novafreek6872 Would it be OK to spray on reduced epoxy then lightly sand it with 600 before my topcoat?
05-08-2012 05:12 AM
deadbodyman same here...but if you have some epoxy already it makes a great sealer when its reduced..

Dave C. IMO I would not worry and spray the base over it.
