Paint eating itself alive
Tuesday, September 18, 2007 12:10 PM
i noticed it starting awHile ago but never thought it was bad. my paint/clearcoat seems to be destroying itself, and in really weird places. anyone have any ideas why?


Drivers side right where door and roof meet:

Just behind my sunroof

my b- pillars





My car may run 18s, but I can do your taxes in 10 seconds flat.
JBO lube - they would never have enough in stock and we'd never see RodimusPrime again

Happening to my mom's car as well.. only thing that comes to mind is improper protection like waxing or something? the B-pillars seem to do that alot but i figure because you dont wax them, they just dont seem like you should wax them. But like i said the only thing i can come up with is its not waxed good enough or do you even wax it? believe recommendations are atleast wax twice a year(Spring and fall)

the pillars.... completely normal...

The clear... not so normal. Normally a regular waxing will prevent that from happening, sometimes it's just a defect from the factory. Once it starts there's really no way of stopping it, except for repainting.

same problem with mine. black cars suck. you can see the clear coming off better on black cars. mine are all in the same places as well. start saving for that paint job

Even if that was true... he lives up north with the rest of us yankees LOL

but no... "sun constantly shining" has nothing to do with it... it has to do with caring for your car properly (i.e. regular cleaning and waxings, etc), and sometimes it can be due to factory paint defects, or bad repair work

its basically a "Sunburn" on your car. Like nikki said waxing the car regularly would have prevented it. Only way to get rid of it is a repaint. the B-pillars are normal just take them off and sand them and spray paint them, or have nikki do it. While your at it just spray paint that nice looking hood you have sitting in the garage and slap it on.

It is called delamination. It's from the sun beating down on your car and not having it waxed. That is why it is only on the top sections of the car.

ha i should take a pic of my car, i would have you all beat. its on my roof, pillars (b & c) quarter panels and fenders. doesnt really bother me though because its now my beater. i figured it was from not washing it or taking care of it.

would a possible re-clearing the car fix the problem?

I think I got my terms mixed up. It is called oxidation I think.
Yah a reclear would take care of the problem but you would still have to do a base before the clear.

base coat for the fact that where there is no clear anymore, the sun could of possibly faded the base paint in that area?

Partially... besides... it should NOT cost anymore to base/clear than to just clear... it's really the same amount of prep work really. Normally shops charge parts and labor... and the cost of paint and materials in normally factored into what they charge for the labor rate. There may be an exception for specialty paints (i.e. chamelions, kandy/candee paints, etc), but "stock" paints shouldn't be charged seperately.


Zspeed: I never really learned a ton of technical terms in my auto body career (I was taught by someone in the business for 30 years, never really got into many technical terms, only the really important ones... my teachings were more based on troubleshooting the problem and fixing it properly and doing quality work)

I've heard it called oxidation, but delamination seems to fit the bill too...

de·lam·i·na·tion (dē-lām'ə-nā'shən) Pronunciation Key
n.

1. The act of splitting or separating a laminate into layers.
2. Embryology The splitting of the blastoderm into two layers of cells to form a gastrula.

Clear coat is basically a laminate of sorts, it's primary job is to protect the base coat, and when clear does that it is separating from the base gradually... so it does make sense but I could be wrong as well.

Oxidation PRIMARILY refers to a chemical combining with oxygen, like rusting, or a molecule's process of losing electrons.

ox·i·da·tion (ŏk'sĭ-dā'shən) Pronunciation Key
n.

1. The combination of a substance with oxygen.
2. A reaction in which the atoms in an element lose electrons and the valence of the element is correspondingly increased.

ox·i·da·tion /ɒksɪˈdeɪʃən/ Pronunciation Key - Show Spelled Pronunciation[ok-si-dey-shuhn] Pronunciation Key - Show IPA Pronunciation
–noun Chemistry.
1. the process or result of oxidizing.
2. the deposit that forms on the surface of a metal as it oxidizes.


Maybe big daddy can clear that up, I trust his word more than anyone else's on this site when it comes to body stuff, he's got 10 years of experience on me. He may come off short sometimes but the man definately knows his stuff. If I don't know the answer to something that's who I go to. (I know more than enough, but I don't even know everything there is)

Happened to my Sunbird in the same spots about a year after I painted it...we decided it was water getting under the clear and eating it away...dont know about factory paint, though...could just be improper protection like others have said...

what everyone calls "b-pillars" is actually incorrect the correct term is door frame applique i dont see a door hinges on it i dont see it metting with the inner and outer rocker panles dont believe me look it up DOOR FRAME APPLIQUE
delamantion was real big in the early to later 90`s every manurfactuer used a water bourne sealer well water bourne and urathene dont mix and the result was paint blowing off in sheets, it looks more like real bad oxidation/delamantion
i still do side work you want it fixed i will do it for a small fee

lol funny cause i had the same problem on my car and i waxed it all the time. in fact you could almost say i overwaxed it. only time i didn't wax it was during the winter when it was too cold to wash and wax it. i think its a common thing with the @!#$ty clear coats jobs on chevy's
