Ideally you want to media blast whatever it is you intend to spray, however not everyone has access to a compressor and blast gun. (I don't use a cabinet, the stuff I blast is so small I just let the media go into the yard haha). Substitute some 400 grit sand paper in that case.
Here are the general steps I take.
1. Acetone Clean Item (don't let sit on plastic for long)
2. Prep Item (Media Blast or Sandpaper)
3. Rubber Gloves
4. Degrease Item
5. Acetone Clean Item
6. (Optional) Bake in (toaster) oven for 15 minutes at 300 degrees if metal (this burns off any remaining residue)
7. Prep Item (Masking Tape, etc etc.)
8. Mix DuraCoat
9. Spray to desired thickness (lay light on tight areas, like where sights go, or moving parts, etc etc)
10. Let Stand for 1 Hour
11. (Optional) Bake in (toaster) oven for 20 minutes at 250 degrees if metal
12. Transfer to "hands off area" (in my case a Husky floor cabinet packed with anti-moisture items)
13. Let sit for 2 weeks
15. Go Play
People ask why I do the toaster oven after spraying since DuraCoat air cures. Simply put, the quick trip in the toaster oven speeds up the initial top layer curing and just gives you some extra protection when transfering the items to their resting place. Its like letting it sit for another hour in the air, but same results in 20 minutes by heating it up a bit. This will NOT speed up the overall curing process.
DuraCoat continues to cure even past 30 days on a molecular level. It actually continues to cure for months. The older it gets, the more resistant it becomes.
DuraCoat says you can reassemble after 24 hours and its ready for average use in 72 hours - but this in my opinion is the absolute bare minimum. You will be much more satisified with the durability if you give it 2 weeks before use. I'd say assembly after 24 hours is fine if you are careful, but still let it sit for the 2 weeks.
Some people just can't wait that long, but patience is a virtue and the end results are more enjoyable.
DuraCoat may appear to be cured on the outside, but the under coating still has some time to go.
