For new painters.
Everyone thinks they need a high build primer but do you?
The low grade companies have destroyed the name calling their 30 dollar primer high build catering to the learning or do it yourself new painter.
Lets take a 69 Camaro as I see a lot of these in shops, the fenders need minor body work, usually a new skin is put on the door, do you need high build here? No!
Standard procedure may be, spray three coats of primer, block with 180 and re-prime to finish out getting ready for paint.
Could you do this with the high build? Yes but it will take more sandpaper and time to smooth out and unless you need the extra exercise, its a lot of wasted time.
What about the quarter that you had to wipe the whole panel with filler to save, that is where you need high build.
3 coats of high build = 4 coats of regular build, so if only one panel needs high build, why not just do 4 coats of regular build and with proper flash times, you will be in fine shape and save a little money.
Most questions like this come from newer painters doing work at home, so we spend a lot of time trying to explain this and since I was just slaughtered on another forum because James brought this up to a newer guy to save him $40, I thought I would post.
Regular build means, "industry standard" In other words, if you buy the majors good grade 2k primer and spray with the same gun, fill will be very close.
There is a need for both primers and it all depends what you are working on.
