Hey Tony,
for your car I would use -->Duplicolor "universal black" truck paint (big can), lays really smooth, no runs..follow w/ clear coat while the paint is still tacky..

I don't know if you remember when my coupe was black...
i did my engine bay & door jambs, nobody could tell it was spray bombed

Before you paint, wet sand /soap & water with 320 or 400 grit,
wipe everything down with laquer thinner...
I usually spray the paint until it looks wet, then back off for maybe 5-10min... It's getting cold outside, so after you spray it, hit it with a heat gun...

practice on a trash can or something that doesn't matter
before you spray your car, practice makes perfect

 

I have a power sander I started of with 100 grit then 320, 400, then 800 grit. What are you planning on doing. do you really want to take that tar out because your road noise level well go up, and it will suck

 

being able to hear the road makes the car perform better

I like the guys idea about duplicolor black w/ clear. clear coat makes the difference with spray bomb jobs.

 

thanks guys
