I just sprayed my k30 with Omni 2 stage paint... Omni is distributed by PPG...made by the Mexicans... so..it's about 1/3 the price of PPG. For the color (Black), clear, hardeners and reducers... (in Gal.) I spent about $235.00. So this product line is pretty affordable. PPG would cost $140 for just the color!!! Before paint...I preped the the metal with PPG DPLF 90...then sprayed a filler primer k36. Then after a day of dry time...I sanded the surface with #220 DA. After the truck cab was sanded inside and out...I cleaned with alcohol and thinner (for Bare metal). Then blew the dust...for about 2 hours..until no dust could be seen. I let the dust settle...and started fresh the next day...by tacking-off the surface. Now....it's finally time to spray... First...since I DAed the surface with #220...and I have bare metal.. I aplied 2 coats of reduced DPLF 90 for a black sealer..and let it flash for an hour. After sanding the dirt nubs..lightly..it's time for color!!! I sprayed 2 coats of color...let that flash for an hour.. then went on to the clear...and sprayed 3 coats. I purchased 2 different hardeners..fast and slow... The first couple coats I used 75% fast and 25% slow hardener.. Then I went to a 25% fast and 75% slow hardener for the last coat..for more flow..to help with overspray. Well....here's what it looked like after 2:00AM last sunday morning... I turned off the lights around 3:00AM. Now...it's time to rub...and assemble.
