I'm using a full service body shop, my cousin is the owner/operator and has done many custom jobs and bodywork in this area. Gorgeous work, he's been my guide. I hit the damaged plastics w/ the DA grinder, followed by 80gr. Fiberglassed the front turn signal portions (one side had a giant hole that looked like someone attempted to repair as well as other road rash on other places), Applied bondo, then mud. Re-80gr the fairing repair to level. Then scuffed all the plastics w/ 180 using the DA sander and used a red scotchbrite on the corners & any other remaining shiny areas, then primer. Next I'll either scuff the primer w/ 320 and apply sealant, and scuff again, or seal the primer and then scuff (whichever he says), but color application will follow, then clear, then another sanding and finish with painting the stencils, clearing them, sanding them, and then applying texture. ACTUALLY THE SEALANT IS OUT OF ORDER IN THESE INSTRUCTIONS. All in all it adds up to tedious. Takes patience, hurry up and wait, lots of sanding pads, lots of elbow grease (even using DA's, and especially the scotchbrite), but it's not AS bad as it sounds. Requires attention and time for expected results. 4 colors = lots of paint for a small job, 1 quart urethane clear, 1 quart textured clear, + all hardners, fiberglass, catalyst, thinners, bondo, & mud or duraglass
