My preparation for the powdercoat consisted of;
- wash in simple green and 90 celcius water
- media blast with walnut shells
- soak in simple green and hot hot water and scrub
- rinse many times
- offgas the parts by baking them in the over at 425 for 30 minutes and cool slowly. I couldnt beliece how much oil had soaked into the aluminum. I opened the oven every few minutes to let the smoke out, it was definately motor oil burning off.
- wash with 99% alcohol
