on this website theres a products page/how to use/perfect paint job. then it comes to the statement that says normal sanding and buffing, what is the norm. im going to use a metallic paint. i guess what im wondering is what grit to use on the 2k primer right before the basecoat, and do you sand metallic paint or just the clear? is there a easy way to explain how to go at this? i wish this would have been included in that article to give something to go with.
