Hello,
Interior paint- Krylon fusion for the hard plastic. I have also painted the radio bezel with color matching urethane Bc/cc, although i don't have pictures of that
The rubbery part on the door- There are two parts
for the upper part I drilled out the rivets on the backside of the door panel and covered it with black vinyl.
for the armrest part, I just ripped off the foam and rubber surround. What you see is just the hard plastic part, painted with gloss krylon fusion.

Headliner kit found at Jcwhitney.com

Thanks for the kind words

Edit to add- If you redo your headliner, make sure to use the correct glue. At first I used a general purpose fabric ashesive and my head liner fell down. I then switch to 3m Super trim adhesive for heavy headliners and its great.

Hey man, i was wondering what paint you used for the interior especially that rubbery/leathery part? and how you re did your headliner everything looks great!
