I purchased a bcm blemished upper recently and the complete finish is off plus it has large 4 inch long sections of bare aluminum. Does anyone have any pointers on refinishing this before assembly?

Disappointing to hear it was that bad. My BCM blem had one minor scratch that I was perfectly fine with given it was for a carry gun. Krylon is perfectly fine, if want something more durable Brownell's Aluma-hyde is a solid choice.
I'd tape off and or stuff the inside with paper to keep overspray off the teflon coating inside the upper.

I'm not even sure I'm going to use this upper any longer. I also noticed the M4 feed ramps are barely there. My Colt and Vision defense upper ramps are much larger and cleaner. Any how I contacted BCA and they emailed me back very fast asking for pictures. Hopefully they rectify the situation.

Those are two entirely different companies and would explain some of your problems if it's BCA vs an actual BCM.NRA Basic, Pistol, Rifle, Shotgun, RSO

Here is what my barrel looks like in the upper. Do you guys think the feed ramps look acceptable? If so I'll probably be able to make this upper work.
