i use Sherwin Williams products.
i use there P30 set-up and love it,very expensive but some of the finest 2k primer i have ever used.
as far as Epoxy SPI is top dog for me.
in collision repair i just don't have the time to use it from start to finish.
all Bare metal should have Epoxy cover it then go from there with whatever you want.
i always seal either with my P30 converted to sealer or Epoxy.
Don't think that I'm some amateur who just grabbed gun in his hand. I've been painting, doing bodywork for good 15 years now. I have used many different primers, expensive PPG K36 and compared to K36 Finish 1 is great primer for fraction of a price (and I get it at discount from local SW dealer)
I'm sure there are more expensive products out there but for repairs this works just great.
I do use SPI epoxy and yes it's great product. It is too expensive to use as a high build primer though and I have 2k primer for just that purpose.
