I used PPG DP60LF on the cab of my 37 Chevy truck and really like the product. I have finished all the dent work and now spraying with PPG K36 primer and sanding it. After sanding, I will seal with PPG DP60LF and add DX870 reducer. This is what my PPG dealer advised me to do. The only difference between DP60 and DP90 is the color. DP60 is blue, DP90 is gray. I will use PPG DCC for the final top coats. I have used PPG products in the past and am very satisfied.
