Just finished wet sanding everything, then wiped everything down with acholol pads to get any of the dirt off to make the paint apply better without any little dirt specs in it. The black piece that has the XL on it was rough unlike the other ones that were smooth, i sanded it down so it is smooth like the rest with 600 grit. I should have done it with 320 grit then finished with 600 to smooth it out but alittle extra elbow grease never hurts anything... Be very careful with the 2 metal trim pieces they bend very easily and are a pain to bend back. When you wet sand the smooth pieces you dont need to apply much pressure because you the surface is already smooth you just need to get that clear coating on it off. After the second coat of primer i will post up pictures.
