Arrgh... Previous owners should be flogged...
I bought an 85 torch red and someone had sprayed (and i use this loosely) some kind of soft white paint on it.. I at first thought it was paint, but its soft and laquer thinner or gasoline disolve it..plus it sands like crap, plugs the paper up, so on the advice of the paint store i sprayed it with Dupont omni pimer and sealer then the Basecoat/clearcoat omni product..While i was spraying it the basecoat started wrinkling and orange peeling within minutes.

Now the primer sealer had been on for several days and was glass smooth with no sign of this.. but the color coat is lifting it right off the car.. Any suggestions for a sealer? the Omni product obviously didn't work.

I have no idea what the PO sprayed on the car.. but short of stripping the car it aint coming off.. and i am not stripping this budget racer, It will just have to be ugly and fast if thats the only option.

Why do i do this to myself../facepalm

 

The more band-aids you apply now, the uglier it will get. The solvents in the base/clear ate whatever was underneath, and the only way to fix it now is to take it ALL off. Colin Chapman hated to paint his race cars because making them shiny added weight but did not improve performance... how about a fast, bare glass, race car?

 

yeah, you sprayed over something you shouldnt have. it wasnt the omni product that didnt work. your paint ppl gave you bad advice. prime isnt that strong of a chemical compared to the bc/cc. the primer sat down fine but when the bc tried to grab hold of the primer, it lifted it all off. the wrinkling and orange peel you mention sounds like lifting. instead of biting into the surface, it pulled it up. stripping it will have to be the next step, unless you dont care, then rock it the way it is.

hey at least when you win, you can say that "you got beat by that ugly car!!??"

 

Like mentioned in the above posts....but not in so many words. It all deals with the foundation that you are trying to spray on. Knowing that it was soft and "gummy". The paint store screwed you royally. But with you NOT wanting to strip it. I do not know what to say....because with the undercoats(previous paint, etc) being soft and gummy. it is going to be really hard to get anything to work well and last for any length of time. That soft and gummy state would have been a RED FLAG for me...and I would have stripped it off...first thing.

You have to look at it like this. If your were building your house... and your lot that you bought was all quick sand. It would be pointless to start building your house due to the foundation will not do its job. So you would have to spend alot of money on driving poles into the ground until you hit soild bed rock and then build your house above the ground.

There are some products out there that will aid in covering and sealing off bad paint issues. BUT I have never used them on a surface that was soft and gummy. That is telling me that it is NOT CURED...for whatever reason....and needs to be removed. Only because anything you apply on this soft surface will crack and have problems due to the soft layer is not an acceptable surface for you to paint on. I know it is on a budget race car...so the choice is yours...like mentioned. Leave it alone.....or fix it.

"DUB"

 

Thanks for the feedback guys.. I appreciate it, And more than likely I will give in and strip it..maybe next winters project.

The existing paint isnt really soft or Gummy.. it looked like white enamel primer. but the fact that it could be removed with laquer thinner should have made me realize it wasnt gonna end well. the areas that lifted are bad enough and numerous enough that i think ill just sand it and reprime it for this season (bout like I did when i was 16)

Thanks again though.

 

take one panel at a time, then seal it. that way you dont get overwhelmed.

 

Bondami,

I recently had something similar on my car. It had 3 coats of primer/paint, and four in other areas of repair. It was very difficult to sand as it would clog the sander even with 80 grit. I had tried a razor blade, but that only worked in two areas. The paint just wouldn't scrape, I tried scraping with a heat gun and it worked great. What took me 3 hrs to d/a I now did in about 45min. I have worked on it a couple hours at a time and now I'm ready to do a light sanding. I had to be veery careful at the bonding strip area and in some cases I will have to sand other,but very little. There were some areas where there was shotty repair that I have removed and grafted in a factory piece. Way more work than I expected, but it has been a good learning experience. Becareful with the heat and becareful not to gouge. I'll do a light block sand, epoxy prime, prime for blocking, then base/clear. This is just a driver for me, so not real critical, but I have a 64 waiting for attention that should be easier, I hope.
