Barry im planning on painting my 62 sunliner with rm uno-hd single stage white. Id like to use the spi undercoat system . the car has been stripped but not sanded yet ( Waiting to hear from you). I will sand w/ 80 grit on a mudhog the use spi gray epoxy primer. Which 2k primer surfacer should i use? Turbo or the other one?Being that the car is down to bm is a sealer really neccessary?Ive heard epoxy used as a sealer negatively affects doi.I will apply 3 coat ss uno hd wait a few days wet sand w/ 800 grit then apply 3 more coats mixed 50/50 with spi clear .Which clear should i use .?I will also be following THE PERFECT PAINT JOB TO THE LETTER. Hey if Keith Ferguson and jim from extreme creations reccomends SPI im a believer. This will be my 5th paint job so im brimming with confidence. thanks mike
