I'm in. I have been doing body work and painting for 40 years. I am no professional, but I'm pretty good. There are a LOT of videos on YouTube about body work and painting. About 75% of them are garbage produced by no talent hacks who have you fill up a rust hole with steel wool and Bondo. If I (or any of you) come across a good one, let's share the link. Good body work and primer/prep is the key. I usually spend about as much time spraying primer, block sanding primer and fixing irregularities found as I do on the actual body work. Now major rust repair is a different matter. The YouTube channel Fitzee's Fabrications is an excellent source on rust repair. I think we might want to break it down into Rust Repair, Panel Replacement, Body work to include dents and body work needed after rust repairs and panel replacement emphasis on proper filler use), priming (including types of primers to use), block sanding primer, filling and sanding minor imperfections found during block sanding, final prep, painting and color sand/polish. That sounds like a lot, but those stages seem like a natural progression to me.
@TrailBeast mentioned a concern that there could some negative comments aimed at members work and that it could become like some of the "which spark to use" arguments. I think that is a valid point. I would just like to remind people that the idea is to HELP others here. We can prefer different types of primer (that's why there is more than one brand), but I don't like hearing people making snide comments about the brand I like. I like Evercoat primers, you like Upol primers and he likes PPG primers. They are all good and will block sand just fine. Same way with other products like sandpaper and paint. This could be fun.
