Another thing, i'm going to show how to shrink stretched metal in my blue car's build thread. I guess it would be a good idea to show how i do it here as well.
My test subject is the hood to my blue car that was a little rough in the first place, then i took it to my media blasters to have them clean the paint around the edges and the supports underneath.
Well, the blasters got in a hurry and just blasted the entire underneath side
. This warped the hell out of the flat unsupported surface of the hood. Sandblasting creates a lot of heat on metal, thin surfaces like a hood skin should never be blasted with sand, use something like crushed walnut shells or soda blasting.
I'll get a picture of the tools i'm using and a couple of me working out one of the larger warps. You'll see in the pictures i'm posting that i've already been working on it.
Make no mistake about this, it takes time. You won't fix something as ugly as this real fast. There will be mud....
Why don't i just buy another hood? They cost $550 new, and that's for an aftermarket hood that may not fit properly, besides, i don't have $550
.
A couple pictures, one of before sandblasting, after, and one of it worked on a bit with it having been etch primered and given a couple coats of primer to prevent rust.
If i have time, i'm going to take out the big one on the right side and the smaller one in the middle today.
