I'm nervous to say the least about this paint job. This car will never leave my stable as long as I have a drivers license. It's a BMW E36 M3. The paint is single stage and is in very good condition with exception to the hood. There is virtually no orange peel and I hope to have it back the same way. They will be spraying the entire roof, driver door and hood. I'd imagine they will have to blend the front driver quarter and possibly rear quarter. I have probably 20-25 chips on the front of the hood that I'm going to have to prep myself. The hood is not part of the insurance claim, so to minimize cost out of pocket, I'm going to sand-prep the hood myself. I have a good friend who has done a bunch of body work in a shop in the past that is going to help me prep it. On a single stage paint, how much sanding will need to be done by them before spraying? I realize that chips are a whole differant deal, but the paint on the roof and door is pretty clean. Does anyone have a good painting 101 site I can get aquanted with the process of prep/painting before I take it there? Thanks for replies.
