- For the best profile from sand blasting use 3060 Black Oxide or 120 Grit Aluminum Oxide.
- Heavy blasting abrasives are not recommended because they leave a poor profile on the metal for painting and can
cause painting defects such as pinholes.
- Blasting is not required if parts are raw material or have been previously powder coated.
- Raw Material: Use All Prep (Iron Phophate) for cleaning and phosphating.
- Powder Coated Items: Lightly scuff the powder paint with a light grit sandpaper (220 grit) and powder coat over the
- top of the old powder. Preheating the part(s) to 125-175F will help powder adhere to the part.
- For aluminum parts or bad outgassing parts we recommend our Out Gass Builder Primer (W6779001).
2. To promote powder adhesion to the metal when powder coating, we highly recommend spraying All Prep (Iron Phosphate) to
your parts and rinse after 30 seconds.
3. Parts can be air blowed off or be placed in the oven to dry if you need them in a rush.
