I did this wrecker last year for my friend, I used SPI black base coat with 3 coats of Euro 5000 and cut 2 days later with 800 grit then 3 more coats of Euro 5000. I denibbed 2 days after and cut and buffed, I was happy with the results but I am no pro.I could'nt advise one way or the other on ss or BC CC but you are in the right place to get information!
