Juice, I looked into doing cerakote a while back and it was pretty expensive. Can I ask you to guess at what it would take to setup something to do small parts like pistols now a days. I've done molly resin, duracote, gunkote, hot bluing, and parkerizing before and have what's needed for those precesses.
shaggy, if you want to do something like duracote, gunkote, or moly resin you will need a way to remove the old finish, sand blasting is the best. FYI not bead basting. Blast the metal parts only. Not the polymer.
Polymer just degrease real good.
Then you need:
1. rubber golves
2. air brush. I used a cheap harbor freight one
3. acetone to degrease the parts.
4. finish (molly resin, duracote, gunkote etc..)
5. black wire to hang the parts to paint and dry.
I personally like molly resin it's the toughest finish I've used. Draw back is you have to bake it so it's not polymer friendly.
If your baking I would suggest going to a thrift shop and getting a used toaster oven large enough to fit you parts and a good thermometer.
