I have used many gallons of their primer and clear coat.I was sceptical in the begining but their products seem to do a really good job.I actually have a 91 Nissan painted using their primers and clears.The primer numbers are not coming to mind but the MS-53 clear is their clear to use.I dealt with a guy named Lou in their sales dept.Give Lou a call and he will give you some info on their products and may even send you out a sample to use.
