undercarriage semi gloss black

[1968 nova ss]

Thanks for all the help and advice.. I ended going with a PPG DCC 9300 black,which is an acrylic urethane. with a 4985 flattening agent,dcx 61 hardener and a DT reducer... I like the semi gloss look...was slightly more than a semi gloss, but I would add a few ounces of flattener on the final coat to tone it down a little.always remember what each product role is on the formula...it you add more hardener it will get more shiner..i also used a DT 885 reducer that is used for some hot temperature . it dryer slower and will give you more time to spray the underneath of car. with it drying evenly..will post some pix hopefully tomorrow.
