Can Aluma Hyde be applied with a brush, or does it have to be sprayed on? Thanks.

The best way to think of Alumahyde is like spray paint that just happens to be resistant to most aggressive gun cleaning chemicals.  I think it's fine for furniture and maybe as an external metal coloring finish, but I'm skeptical of its utility on any metal parts that are going to see mechanical friction/wear.  I used it to color a synthetic folding stock for a Marlin Camp Carbine, and after allowing it to fully cure, it still chipped a little bit where the stock rubs against the charging handle when folded.  I don't think anything disastrous would happen if you brushed it on, but I'm not sure why one would want to.  Is there some specific application you have in mind that causes you to ask?

Seems to me like that would work.  I wonder... I read somewhere on this forum that Ident uses Aluminum Black to fill the engraving on the NDS gray receivers they do with the Colt markings, Auto marking, etc.  I wonder if it would be suitable for touching up scratches, or would it really be too black?

The main thing to remember is that they aren't kidding when they say it takes 1-2 weeks to fully cure.

This rifle won't be shot for at least another month or so, so that's not a big deal. Shooting is too expensive.

Plinkster, you are worried about a freakin scratch?   Anyways  

I used Aluma-Hyde II on my Retro trench gun build and it holds up well.  The spray nozzle clogs up very easily though so make sure you have some acetone or alcohol to clean the cap with.

Edit:  I painted the receiver with flat black

+1 on the clogged nozzles.  I just pick up half a dozen replacement nozzles whenever I buy a can of Alumahyde.  Actually, I usually get several cans at a time because of the hazmat fee...

just answered you e-mail before logging in and reading this

looks like everything I told you was already covered here, except like I told you in the e-mail, if you use multiple coats (more than 2-3), like on a stock, extend the time allowed for it to fully cure before you even touch it.

for just touching up a scratch I don't see why using a small fine artist type brush wouldn't work, I assumed you were talking about apply the finish to a larger surface, such as a stock or receiver. For just a touch-up a single light coat would probably be sufficient

Just noticed this... You're probably already on top of this, but just in case... there is "parkerizing gray" and there is "dark parkerizing gray", and if I recall correctly from previous threads it is the dark variety that best matches Colt / NDS / US Anodizing parts.

I was aware of the variations, but I went with parkerizing grey instead of dark parkerizing grey because I'm trying to match it up with XM grey, which is pretty light on my receiver.

I got my parkerizing grey (not dark parkerizing grey) Aluma-Hyde the other day and applied it today. It's a PERFECT color match for U.S. Anodizing's/NoDak's XM grey. I'm quite pleased.

Oh, I had plenty of tape on those vise grips, but the teeth bit through it anyway. The phrase "pissed off" doesn't even describe how I felt. I have since found a much better way to go about putting them in.

I bought one of RL's kits.It's a handy little kit to have.I never have an issue with installing the bolt catch but I've done several M16's and people are always bringing their AR's by the shop for us to assemble so I guess I get plenty of practice.Oh and plinker don't worry about the scratch.It's hardly noticeable and you did a great job with the Aluma hyde II.

I've never been in the military (wish I was), but I just like to keep things uniform. Well, that and my dad (who was an M60 gunner back in the early 60's) taught me discipline from a very young age.

Cda, a good slap just might do the trick.

I painted a plastic FAL stock with Alumahyde.  After proper prep and some light scuffing that stuff seemed to have actually bonded into the plastic.  Maybe the solvent was enough to temporarily gum it up while the paint cured and now it won't come off without removing plastic, too.  I have not been terribly impressed with its durability on metal parts.  Anodized aluminum has pretty good "tooth" to it so maybe it'll hold better.  Fresh dry parkerizing would probably hold it OK, too.

Good point. Drying time won't matter to me anyways because that rifle will not be shot for a while. None of my AR's will.

Thanks M1.  The covered vise grips work great for the trigger guard, but I have found the best method for the bolt catch is a slabside roll pin punch from Brownell's.  They run about $15 though and that is why they were never in the kits.  If you use the vise grip method on the bolt catch chances are it will produce those scratches, especially if the vise grips are new with sharp teeth.  They tend to eat through the covers and tape before you notice it.  It's mostly caused by the small, angled boss causing the left side of the vise grips to roll  and/or slide off when you apply pressure.

A cheap way to do it is drill a shallow hole in the end of a clevis pin or a door hinge pin and use it as a holder/punch.  The hole in the clevis pin keeps it from slipping off the roll pin and gouging the lower.

Also, I know you guys have built a lot more lowers than I have, but the one thing I find that helps the most is putting the front of the lower up against something solid when you are tapping the bolt catch roll pin.  It provides a solid force to the pin and keeps the lower from bouncing around, reducing the risk of the punch slipping.  Similar to removing FSB pins on a covered concrete base rather than on a flexible bench top.

The slabside bolt catch punch is great for removing the pins, too.
