Hey, Fellas
New guy here.
Been in the autobody fixit biz for over 30+ years and have also painted custom Harleys with both laquer and base/clear systems. But have no idea what "SPI" paint products are. Can you put that in English for this new kid on the block?....RooDog

PS: I'm currently using Glasurit base/clear cause that what the dealership I last worked in was using.....
