I bought the kit from Brownells in magpul FDE.

I plan on doing a stripped upper, lower, and FF handguard.

Here are my questions:

1)  Do I install the upper receiver parts first before cerakoting?  The dust cover and forward assist?  Or do them seperate?

2)  Are there any places on the stripped upper or  stripped lower receiver that I need to mask off?

3)  Do I coat the insides of the upper and lower?

4)  Can I bake these in my old ladys oven without ruining the oven?  This is the most important question.    If I bake them in her oven and her cookies taste like cerakote, I will need to find a new place to live.

Take EVERYTHING apart. No two parts need to be together at all.  Soak in acetone for twenty minutes or so. Then, take that dust cover, bake it at 200 for about a half hour, then soak it again, then do both a few more times until no grease comes out.

Then blast everything with 100 or 120 grit aluminum oxide, then, just in case, after you clean it all with compressed air, bake everything for twenty minutes. If any trace of oil or grease shows up, start over.

The problem with baking in your wife's oven is that it will be damned hard to hang everything where it doesn't touch anything, and you won't be able to get any of it far enough away from the element to ensure it won't bubble. I've seen that happen before. Then your whole house will smell like cerakote. (aka, money).

Good tips on the prep.  I've heard thats 90% of the battle.  I'll take care to do it right.

What about masking anything off once its stripped of parts?  Cerakote the barrel nut threads?

Do I spray the insides of the parts too?

The threads will be ok, plug the holes in the lower and the take down and pivot lugs in the upper. I generally don't tape off the inside and just let over spray get in, but I usually go with what the customer wants.

Good tips on the dust cover. The first soak / bake doesn't always get all the oil out of those things!

I have a theory that there is some type of indefinite supply of oil inside dust covers.

If we ever run low on fossil fuels, we can probably wrangle up all the old dust covers and figure out way to milk them of oil. Sure an endless supply.

Factory standard is 5.7 barrels of sweet crude. . .

Thank you all for helping me realize I will probably always need to send my stuff to somebody qualified.
