    Going rounds with a painter. First paint job had bugs, runs, fisheyes, etc. The doors and rumble seat you could see black dots all over. Almost like he reduced it down too much to spread the paint out more.
    Well, now I got my aluminum parts back, after round 2. Meaning hood, louvered sides and rear roll pan. I rubbed my finger down the edge and the pain just came off. This was painted 2 weeks ago and has been sitting. Any ideas why this paint just falls off the edges when pressure is applied?

    Aluminum needs a special etching primer. It's usually green in color.

  3. Not an expert by far, but maybe find another painter. If you're having issues like this now, the whole job will haunt you.

    Improper prep on the alum parts. We sand all surfaces, clean and apply epoxy primer on all alum parts. Never had an adhesion problem doing it this way.
    Based on your photos I would find another painter.
     
  6. Paint fell off because it wasnt prepped properly or the guy has serious amounts of contamenents in his airlines.
    sounds like it was painted outside if there is bugs in it

    It was a trade deal where I traded him a 2002 mustang gt and holding the title until complete. Got myself stuck in a spot.

    Take the car back, find somebody that knows what they're doing. There's no way this is going to turn out well for you.
     
  9. On aluminum I would clean it well, spray etch first, and epoxy over it. You have an adhesion problem....and holy orange peel...gun set up and spray technique will help that. I would say color sand it, but I'm afraid the paint will cone off in sheets.

    Runs....lack of skill
    Fisheyes...something in the air, improper cleaning of surface, contaminants in the lines
    Bugs..happens in a garage job
    Black dots? Maybe solvent pop?

    Sounds like his guy is learning to paint on your ride.

    He was a good acquaintance and let him park the car at his shop since I had no room for it. He started driving it and tags are expired so he parked it. I called police and nothing I can do here in my city since I "borrowed" him the car. Meaning if I decide to walk away, I will have to go to court to get mustang back and if I get it back, who knows what will be poured down the tank.
    Gave him chance to fix it and still having issues. He has been painting for 20 something years and his shop isn't the best but it's indoors.

  13. So, what you're saying is this guy was essentially paid in advance for a deal he is not delivering on, you can't go get a car that you hold title to, and this guy is such a good "acquaintance" that if you were to back out of the deal, because he obviously is not delivering on his end, that he would exact some sort of retribution by pouring something down the tank. Geez man, doesn't sound like too good of a bargain. If I were you I'd have a talk with him. Pay him for the materials and get your car back. You might take a hit but that is the price of the lesson. I know this sucks. Sorry man.

    Anybody that's been around a paint shop for 20 yrs knows better than to turn out work like that. You are getting the royal shaft... talk to a lawyer.

    It's your car, you have the title. Go pick it up.

    Painting for 20 years, but can't make paint stick to sheet metal? Dude, I'm no painter, but I can get better results than that, myself, with rattle cans.

    Yep I agree with everyone. I got screwed. He seen the pieces and said not to worry that he will fix them. Said it must be the paint and told me that we can bring hood into paint supply store. Sounds like they will let him know it's his fault from what I'm hearing.

    Lesson learned for sure. People sell themselves on their work and I've learned to not trust without further proof. At least I know what is most likely the cause now so if he feeds me bull shit excuses, I can call his bluff. Especially with the supplier looking at it.
    I guess having him tape off everything but the edges and respray is a bad idea. That was his solution. Lol. I'm so screwed.

    Edges require prep and are easily overlooked.
     
  24. Agree with previous comment, pay him the cost of materials at the same time you're driving mustang away.
     
  25. Here you go, go talk to the man in his office were he should have a computer. Take him to H.A.M.B. Let him read this thread & all the replies you have gotten on this issue. He needs to do the right thing emedietly. If striping the hole project & start over would make it right, that's what he needs to do. Shit happens some times when you have a business. It's his fault not yours, any loss is on him. Or cut his loss now, give back the GT & let you go else were to get the job done over right. Friend or not, if he clames to be a professional?

    There may be a couple of guys that could make that work, if they had to, but I'm willing to bet that every one of them would tell you to strip, sand, and prep the piece correctly before painting it again. Any band-aid fix like that is just asking for trouble, and suggesting it tells you everything you need to know.

    Just talked to the guy. Last night he said he etch primed it. Today he told me that he acid washed it and that the paint should stick really good and how the old red paint that he painted over must be peeling. Old paint never had these issues.
    I'm scared that even if he "fixed" the edges, if he doesn't sand all the way down and etch prime it, is there a good chance paint chips off of the flat surface later? Even though it half decent now?
     
  29. Yep you need to use a good zinc primer first on alum. It should be green. If you don't use zinc it won't last as long some of the primers out now will work with alum but nothing beats zinc primer. That's why NASA still uses it....
     
  30. And you need a new painter..
