Raptor Bed lining Tintable & Auto Body paint

[mpierce9]

Hello I have some questions regarding auto body paint and Raptor bed lining. I've followed a few threads but struggled finding details about mixing the tint or locations to purchase auto body paint.

I'd like to spray the interior of a K5 Blazer with Raptor bed lining. However the natural color is black and I feel like that would be too hot inside the truck. I'd like to use the tintable version of this product and tint it a basic gray color. Nothing fancy, i'm just tinting to keep the heat down while the top is off.

My questions are:

1. Where can I purchase basic Gray paint in order to accomplish this?
1b. A local place would be optimal. I live in zip code 30317
2. What type of paint would be best?
3. Has anyone used the tintable Raptor product and do you have any advice?

Just a quick scan of TCPGlobal.com and they have these different types of paint:
AE Acrylic Enamel
AU Acrylic Urethane
AL Acrylic Lacqure
UB Urethane Basecoat
Primers & Clears

There are a ton of options. . . I just want Gray.
