Vinyl that forms to your FG box?

What's up guys?!. Haven't posted here in a while, but the FG box I was building for my 3 15"s in my PT Cruiser is finally complete!.

Originally I was going to paint it, but I couldnt get it all that smooth. But, I was thinking of laying down some type of carpet foam to the curves of my box, then vinyling over that, to create a slightly puffy look (and figuring the foam will hide any of the slight imperfections that I have). Sort of like some door panels on some cars.

Question is, how do I do that?. I thought I read somewhere that you can lay down this certain foam, then lay vinyl down, then use a heatgun to shrink the vinyl to basically form all around the curves on the box. I searched and searched, but can't find where I read that. I even went to selectproducts.com, but found nothing regarding vinyl that forms around what you have when heated.

If a heat shrinking vinyl is no such thing, then how do I do it?. I have seen plenty of FB boxes that are covered with vinyl with some padding underneath.

Any help guys?.

i know the vinyl your looking for, the thin stuff with foam backing that is more like a plastic..... used on doorpanels and headliners alot.  I think that would look sick, would love to try it, BUT, i have no clue where to get it....sorry man

Thanks for the responses so far guys.

I went to Select Products, and I didn't see anything regardling heat forming vinyl, unless i'm losing it. My plan is to get Beige vinyl to match my interior, as well as the same texture like the stock interior.

If I go that route, #1.. how do I get foam to stick to the box (contract cement?), and #2.. how do I get the vinyl to stick to the foam?.

hf vinyl is the heat formable from select products i just checked...$30 a yard though
