Paint Job Gone Bad

i have painted cars for 32 yrs now and there are 3 words to help you with a paint job
" preparation - preparation - preparation"
if you dont do those you can kiss the paint goodbye, you ruined it

 

sorry the above post was to be under my name not mac762, he was using my computer earlier, I have painted for 32 yrs, hes barely 32 LOL , omg im old, ive been painting as long as hes been alive !

 

this was a dupont oil based single stage, had a rep come out and he wasnt sure what had happened. after i fixed it i came to the conclusion my helper at the time picked up some 1200 instead of 400-600 to do the wet sanding

 

Gives new meaning to "STRIPPER"

 

Oh. My. God.

 

Darryl's a hack!


At something I'm sure, but not painting.

Thats some funny **** right there Terri.

Hey, look who I saw this weekend...

 

thats funny! glad i have a pro painter in the family!

 

,,allot of peaple think when prepping a car for paint you need to sand it down to 1000 grit then let it sit in the sun for a day after wet sanding it,then they shoot it,it does not stick,the scrathces flow out,i like to keep 400 - 600 grit as my last grit,then after sitting hit it with a red scotch pad,my paint dont peel,,,,

 

it looks like the vinyl graphic overlays that the small time record labels use to put on cargo vans around here. they usually got some silly gold toofed rapper on the side of it with the ***le of his up and comming album. there wasn't a rapper's face on the trunk, was there? haha

 

x2!

 

That's the funniest part... $100 paint on a million dollar car

 

It took me all day to brush that on and get all the lines out.
And you guys just make fun of me.

 

thats just crazy

 

My thought exactly, I couldnt tell what it is but it sure looked like a damn expensive car !

 

Hey,

This isn't really a rare happening in the paint biz!

Don't read and understand product labels, don't understand what you can and can't get away with with paint solvents and chemicals, allow too long a ''window'' between the time a sealer was sprayed, and the first colour coat, sprayed, all can cause paint failure on this scale.

The fact that this happened to a Delahaye, and that the colour was red, and that the job probably ran into the five figures for labor and materials and I'd be lookin' to make a lampshade out of the painter's or paint reps. hide!

'looks like a bare metal respray from here back, given they dropped the ball on the top coat, no telling what they did or didn't do beneith the non sanded sealer.

From the 70's to the early 90's as paint companies started to market "Tree Hugger Kool-Aid" (waterborne paint), this type of paint failure was very common. Bad binder in the sealer/undercoats, bad binder in the base or clear coat, all resulted in this type of failure.


" Spending a nation into generational debt is not an act of comp***ion"

 

over the years ive actually seen that scenerio many times

1st, it aint cause it's water base paint, in fact the new water base systems stick better than solvent, way better. notwithstsnding the rude factory jobs of the 80's and 90's (that was a sealer issue by the way, not a water issue)

many ways to cause that, but the frequent flyer is to let base, or color(single stage) set too long, then think that sanding with real fine paper such as 1000, then re coat or clear

iv seen many a sherwin williams base job sit, then the painter sands the base and clears it. the clear wont stick to sanded-cured base. it has to be applied within a narrow window when the solvent is out, but its still not hard.
also if you got in a hurry and put it on too fast you get the same results.
over dried sealer can do as well

incompadible sealers, base is another. usually anyones clear will go over anybody's base, but you better know for sure. also dont ever mix brands with catylists

i would guess the painter really wanted to do a good job and did put out a bunch of effort, unfortunatly he was a little short on knowledge, or tried one of the shortcuts.

i actually like it when you can peel the stuff off like that, much cleaner and easier than other methods of stripping , lol.

putting it out in the sun on a warm day will make it really easy to peel by the way

I've seen that happen in the UK, Its caused by letting the basecoat dry too long before overcoating with lacquer. Once the basecoat is put on there is only a small window of time to get the lacquer on, You can't leave it a few days.
A friend of mine painted a roof with basecoat and left it 3 days before lacquering and the same thing happened.

 

Saw this happen recently on some Army equipment. The topcoat was applied over a stripped and well-prepped (they thought) machine. Within a week the paint was peeling in sheets just like this one. It was Sherwin Williams paint so the Sherwin Williams field rep came out and did a restrip, re-prep and repaint. Solved the problem, which was inadequate surface prep. The repaint was fine and the contractor continued doing other machines like Sherwin Williams recommended and haven't had any problems since.

AND - this looks almost like how some NASCAR cars are now done, with large vinyl sheets to cover body panels. Supposedly makes for an easier re-do and time saver. I don't know though, just heard it.

I also remember in the late 70s that Ford had similar issues with paint peeling off new cars within a year or so after sale. It was mostly silver/grey metallic paint colors, and mostly on pickups. Ford authorized re-paints on many affected vehicles covered under warranty at that time but I don't recollect them ever indicating what caused the problem. Most likely something wasn't done right during prep at the factory.

 

gm and chrysler also suffered the same fate

seems in the quest to save money, the factories went with a new system the paint co's ***ured them would work and save coin. it involved skipping a step in the primer-sealer-base-clear that they were using.

skipping that sealer saved alot of money initially, then the repaints clogged the body shops at dealers so much that they were paying independents to redo them. i did many gm re-dos.

i think that the program ended around 2006 for warranty paint, but the bad jobs ran from the late 80's up to late 90's

you still see them on the road peeln and rustin

On a Delahaye?

 

The clear on my Unicover topper is doing that. Good thing it has a lifetime warranty, they are going to reshoot it for me.
