Kevin, I have watched your videos and have really learned a lot. A friend wants me to help him paint his truck and wants it finished in primer as seems to be in vogue nowadays. Can you give me some advice as to what primer I should use (is there a particular one that would give a better lasting finish), should I use my standard 2k PPG primer and should I use some type of a ‘primer sealer’ as a top coat? Any help would be appreciated. phil w.
