Having never done serious bodywork prior to the Locost, I learned a lot in this area. I'll throw a few things out and will elaborate further if anyone wants.
-don't go for flat/satin for your first paint job. It's REALLY hard to get right.
-don't use nitrile gloves with acetone. It eats through and gives a pretty painful chemical burn (cleaning gun out). No burn with bare hands.
-don't use plastic as masking. It causes the overspray to flake off it and gets into the new paint etc.
-custom fibreglass isn't so scary
viewtopic.php?f=23&t=11633-spend money on non-lint rags when cleaning for paint.
-Jack's "Steamroller" fenders work great.
-dzus fasteners are really finicky
-anneal anywhere you are curving aluminum. It makes life much easier.
-green masking tape. No white stuff, it sucks.
-buy waaaaaay more paint,mixing cups,filters etc than you think you need.
-yes, you need filling-primer. No matter what the paint instructions say.
Cheers.
