lol...ok people people we don`t use single stage any more unless for frames, and work trucks, parts stuff like that
to properly fix your rust, 2 chioces i would do
1st: i would lightly grind the rust with my small die grinder
then go over with 80 then 120 then feather edge the paint with 240
i use ppg so i would use 271 it`s a corrosion resistent primer filler
wet sand with 320 then 400 then 600 then use 3m`s prep blend with a grey scuff pad rinse with water and mask off for paint
2nd: sand blast use steps above shortend version
as far as paint is concerned.....base and clear is polyurathene
i charge starting price for a full paint job $3,000 to $6,000
your body work could be strait as an arrow but if your prep work is shit you will have a bad paint job
good prep work is the key!!!!
if you do not use a corrsion resistnet primer you need to use a self etching sealer or a substrate beneath you primer filler
hence the the ppg product ncx 271
a good quality clear for the garage is omni made by ppg
there is still so much more but iam not goin to make this any longer
any more questions feel free to ask
