2K Primers

Look into SPI. I have switched from PPG to SPI and will not go back. The prices are great and the product is top notch. I have had absolutely no problems with compatibilty with any top coat I have used over it. It builds great, sands extremely well, levels quickly, and there is far less shrinkage than PPG's K38. Not to mention if you have a question you will get answers from someone who knows the product line, not some guy that thinks he is an expert body guy at the counter who has never used any of the product in the real world. Now the only draw back is that they are only avaliable through the net from their web site, but still cheaper with shipping than PPG, Dupont, and many others. I have used it with RM, PPG, Dupont, Kirker,and Sherwin WillIams without any issues. Just a note though is that you will still need to seal any primer before applying your top coats.
