how much would you folks suggest reducing 2k spi primer to use as a guide coat. i am spraying grey spi 2k for blocking and I am using the buff spi 2k primer as a guide coat. how much should i thin it to use as a guide coat. i dont want to be sanding for hours to get a thick coat of buff 2k off the car but I dont want to over reduce it and end up creating me more problems. suggestions! being a rookie i am very happy that i have found this site as most other boards seem to give conflicting advise and in some cases incorrect advise. you guys are awesome thanks for your help!
