Here is what I did for $500
prepped
primered then sanded with 400 wet
as I was spraying... it was a light orange base with gold pearl in the first 2 coats of clear.
outside the following day
outside after a nice wetsand/buff job
I sprayed it in kind of a booth... Your garage would prolly turn out better cause the booth was dirty and not made for cars... I think they used to spray funiture in there? It's a construction company and they build walls in there so I was battling dust pretty bad which up close you can see some imperfections but not bad at all...
