We didn't try the heat shrink and went with the cold shrink method using the pick hammer and rubber sanding block dolly

The door panel doesn't pop in and out like before

we caved it in and paved it with a very thin skim of mud and a used a long air sander and got it looking pretty nice.

I used POR 15 on both sides of the new running boards
the inner fenders and front suspension. Still have 1/3Qt. for touch up

great stuff
I sure like the look of that POR 15

thanks for the help
