PPG primer

[Rich G.]

Last 2 cars I did I used PPG DP primer and then  PPG K38 primer after all body work . My supplier has to order the K38 but said he sells DPS3105 now. I called PPG and they said there about the same. Not a very useful answer. Any body people here have and pros or cons on these?

I`ve been using the K36, not sure about the DPS3105 but the writeup sounds good
