I'm getting ready to paint on the mag well on my AR.  I will be using a "high quality" rattle can. I want see if I like it before I do anything permanent. My question is when I put it in the oven to cure can I just remove the grip and leave the rest of the LPK installed or do I need to strip it?  Thanks

you shouldn't have to oven cure "rattle can" paint.  Just clean (degrease) it and spray it on.  Read the directions on the side of the can.

If by mag well you mean the entire lower of an AR, removing parts such as the grip and stock is a little bit more tricky than just unscrewing the screws. There are springs,  detents, and catches that are held in place by the grip and stock.  I suggest you browse your manual and become familiar with all the parts and pits in the gun before you start removing stuff.  It is not difficult at all, but ignorance will get you in trouble.

If you are only spray painting for looks, I would recommend just masking off the areas you don't want painted instead of a complete disassembly.

Make sure to post pictures of your work too.  We all like to see...

The only "curing" of rattle can product is done in my truck on a hot sunny day...usually on the dash.

I built the lower so I do know what is invovled,felt as though I got lucky with it being so easy...didn't want to tempt fate if I didn't have to.

I'm painting a "logo" on the mag well that is somewhat intricate...figured an oven cure on almost any enamel is going to help durability.

I'll post pics when done

"baking" paint that is designed to be self curing will not benefit from it.  A few minutes in the tropical sun does a nice job.  But if it makes you feel better about it, go for it.

OK,let's say I was gonna use DuraBake or something like that could I do it with the LPK installed or not?
