From Experience, You need to...
1. Soak and Clean in a degreaser such as .... the Black jug at Harbor Freight.
2. blast aluminum parts
3. then bake them for 30-60 min
4. let cool
5. blast again
6. wipe down
7. bake again for 30 min
8. then pull part from oven
9. shoot while warm/hot
10. Bake and cure for recommenced time.
This is what I have learned is the best way to do it.
