Hi Everyone,

I have an issue with a recent paint touch-up that I'm trying to understand so I know how to deal with the bodyshop. The shop said that because they don't know what products were used on my car before, this issue is the result of their current products reacting with the old products. But my previous paint work was over 10 years ago. Would "old product" still be reactive?

I had some paint chipped areas and some bad areas of previous paint work where the paint was lifting off the body. I couldn't afford a complete respray so I had the shop fix only the affected areas. When I picked up the car, it was in a rather dark warehouse so I didn't notice any issues. It looked great. And I was swamped so I didn't inspect it out in the sun after pulling the car out of their warehouse. I noticed the issue about a week later. Might this have been fine when I picked the car up and develop over the course of a week?

I took the car back for them to fix the area. All they did was try to buff the area. Now the paint is buffed away and I can see the primer along the ridge of the imperfection. And I now have buff swirls around the imperfection. The swirls are now also on the hood cover. So if they respray, they would have to deal with the hood cover as well. Maybe the hood cover can be color sanded away?

Ideally, for me, I want the shop to redo the area. But that means respraying the entire front clip. I don't want to put more work on the shop than is reasonable. But I want this fixed. How to proceed?

The attached pics are before they buffed the area.

Thanks for any advice,

Manny

looks like a half assed polished run.... also maybe something starting to crack ?

Agree. A run in the primer that they didn't sand out before basecoat. When they tried to fix they've exposed the primer in the high part of the run.

Needs to be rubbed back and resprayed.

Thanks PainterDave and NFT5 for your inputs. Just to confirm, this is not a result of some reaction between different paint products. But more likely was sloppy work prior to color being sprayed. Specifically, not sanding the primer properly before applying color.

And the proper fix is to sand the area down and repaint, correct?

if the run is in the undercoat it will need re painted.

if the run is in clear can sand it flat and polish

It's in the undercoat. I've already taken the car back to them to have them rectify this issue. All they did was try to buff the area resulting in the color being buffed away and revealing the primer. And swirl marks in the surrounding area...including the hood. This is what prompted me to do my own research so I know how to confront them.

always good to give them a chance to fix it. hope it all works out

A new development, the area in question bubbled and cracked. So it wasn't a run?

open that crack up it is probably going to be rusted underneath...

i can see in the first post now it was clearly starting to crack.

that will need grinded out and fixed properly.

It could also be that they applied the primer too heavy without proper flash times. This will cause a blister to form from solvent trapped below.

The only way to really tell is to peel back the chipped area.
There was a blister in this paint job that would raise up when buffing and then go back down. Turned out to be the metal prep I had applied without properly neutralizing it.


Ended up stripping the entire roof and starting over again with epoxy primer.
