Yes sir,......
Some sort of warmth will help on sheets you need to "form" to a shape.... like bends...
I had a heat gun, while doing mine.
BUT, ... as it got later in the day, and the sun came out,... i just tossed em up on the roof of the vcehicle, and put the sun to work for me.
Once the sheets "soak" up a lil heat,... they become wicked more plyable. Much much easier to work with.....
Shit goes on like a dream, and STICKS LIKE A BITCH !... make sure you set it where you want it..lol
I went ape shit.....
Good luck..... get to DEADING man !!!..
