What went wrong? I bought this pickup two weeks ago, owner said it had been repainted but there were a few flaws -- mostly rust spots on hood. I got to working with one of the spots this morning after I had sanded and primed them to stop the rust until I got time to find out what the problem was. One small piece had "flagged" from the sanding so I tried to pull it off. You guessed it -- peeled like an overripe orange Here's part of one of the pieces I peeled off. Here's the hood -- you can see the line between the two pieces I peeled off. Those scratch marks were there beneath the paint. Here's some close-ups of the back side of the paint. Yes, those little white spots are there. Even closer. Did the painter not sand and clean between the gray and the white before the topcoat of red? It was not a base/top coat finish, just a single. I belive the hood was a repop piece to replace the damaged one. What do I do now to make sure it doesn't happen to my paint? (And yes, thoughts of adjusting the at***ude of previous owner with daddy's 1-1/2" combination wrench did p*** through the evil back sections of my mind )
Is this an O/T truck? If so is that a replacement hood? Reason I ask, if it is an replacement hood that comes in Black that stuff has to be sanded off 100% or the paint comes off like that. The other problem that could be is it looks like it was sanded with 600 or finer paper, usually 320- 400 is where we stop.
Might be cheap lacquer based primer over the black... I would take a pressure washer to that hood, probably wont have much stripping to do after that!
Electro plating to keep it from rusting. Primer will let the moisture thru and the metal will still rust.
Could be a aftermarket replacement hood and whomever did not sand the E-coat off before sealing it. The stuff they try to p*** off as E-coat is pure **** and if you dont sand it off, this is what can happen... My first clue was the rust you mentioned. Pretty typical.
Reminds me of high school auto shop. There was a body shop in a nearby town that would paint any car for $39.95 including paint. On of the teachers had a car painted there. He was driving and the paint peeled off the hood and flopped back covered the windshield. He brought it into the auto shop and it looked like the guy didn't even wash the car before he painted it. You never get more than you pay for. I wouldn't buy anything with a fresh paint job unless there is a warranty because you don't know what's under the paint.
My '93 Dodge pickup did the same with factory paint as did my neighbors 2009 GMC pick up. Both white.
I can understand the Dodge, they had problems then... but the 2009 GMC? Waterborne basecoat and urethane clear. It shoulda stuck on the 2009. The EPA pushes the Automakers real hard to eliminate VOC's. The only problem is we are the guinea pigs and have to live with the automakers experimentation.
There are sealers that will stick to e-coat even with out sanding. Spies Hecker, good ****. Lifetime warranty. Obviously that is not good primer. It does look like fairly fine sand scratches but it should have been fine with a decent primer.
De-laminating as they call it, little of NO prep so it won't bond and will continue to peel. The rest as they say is history. You'll have to strip the whole car.
Yeah he came home from work one day with practically a primered truck. All at once. I just bought an '11 GMC in red. Hope it sticks.
If thats a replacement hood, it was probably just sanded with wrong grit, or washed with the wrong type of cleaner before the paint was shot. Lotsa newbies use an automotive washing solvent after sanding instead of final kleen.
The good news is that the rest of the truck seems to be ok -- only the repop hood is bad. But that's bad enough
It's just a cheap paint job to make it look nice so it'll be easy to sell. Once it's yours they don't care what happens to it. Sorry.
As said before da hood ,Down to metal and get start over ,And be thankful it was only the hood,Go to a place that can color match the paint,
I used a bunch of Imron years ago on big trucks. That stuff would adhere to ANYTHING, except lacquer based primer! If it wasn't sealed with with a self etching epoxy based sealer, you were in trouble!
