Hello everyone. I was just wondering if there is anyway to remove "Stress Cracks," can any polish/wax help cover them up, or do I have to repaint the area? Below are pictures attached for reference. Thanks for all the help.

good question. I have those on my subbie and was wondering the same thing.

You'll have to go for a repaint, sorry.

Thanks, That's what i was afraid of. Do you know what they do to have them removed? Do they just sand the area down and then repaint it? Thanks in advance.

It's a Grand Prix, not quite the same as a vette for racing:smack

I was wondering where the hell those body lines were on a 71 vert!:laughing:

I had the same problem on the '74, where the T top bar meets the coupe back.
As I sanded it back I found the cracks only to be in the paint and not the gelcoat, so it was an easy fix.
otherwise I believe it's a matter of scouring out the cracks to be a v shape and fill with resin or gelcoat repair putty or similar....been a while since I read about it but , if you can get a hold of that book " how to restore and modifiy your corvette 68-82" (white soft cover with a blue 70 on the cover I think)
It goes into detail of fixing these problems!

I thought about that but... the cracks are on the rear bumper (where someone kindly bumped into the car in a parking lot and then left before I did), and it's made out of a (ABS?) plastic. I don't think there is enough material to sand down and fill with a resin. I am repainting the front bumper here shortly, so if I just sand it down and then paint over it they might disappear then? Thanks for the help

:thumbsup: OK if it's ABS, the cracks will only be in the paint....ABS will flex whereis FRP will crack in the same way as the paint if flexed far enough!

I doubt very much that you'll have problems with the cracks reappearing if you sand back through the paint and reapplying.

Thanks, That's what I was thinking:thumbsup:
