I painted my 87 toronado (metalic dark red) for 600cdn, but it spend a day with a buffer cuz I did it in a dusty/dirty/greasy shop.
back when I was 16 I had some money saved up (my dad payed for the full restoration of my truck) so I bought the paint. Four thousand bucks... the shop had my truck for 3 months.
-pre acid wash, detergents...
1) They sprayed a thin layer of eching primer
2) sanded it smooth -almost of bare metal
3) second eching-smooth a bit off bare metal
4) third eching- smooth with a bit more off bare metal
5) have the whole thing sit for a month
6) base coat (non-metalic, cheap red) - sanded to smooth (to the point where the eching primer was showing through)
7) base coat 2 again cheap red, just a bit thinker.
sit 2 weeks
9) metalic cherry red (6 thin coats, with wait time in between)
10) sit for 3weeks
11) clear coat, 5 thin coats applyed, with buffing and 'cutting' and waiting in between
Now, You may wonder why have it sit? It gives the paint depth and taking it smooth and then more and more primer? thats too reduce orange peal (GM vehicels have lots of orange peal, because it hids blemishes well)
