powder coating

Depends where you go...

My brother got his frame sand blasted for $20 and sandblasted all the small parts in a box type we borrowed.

Powder coat my guess would be 150-300 Just because you have to pay them for their time...
 
u cant powdercoat stock A-arms safely.... there is a place part that could melt and then u would be in trouble riding along and your wheel falls off, because of that plastic piece.

That plastic part you speak of is within the ball joint, it does not like to be heated much.
