Rustoleum On Alumium Rail

I just got a set of P&S product M4 rail (another contractor that makes the same thing as KAC rails). The finish on the lower rail appear to be faded, like a purple color instead of black.

I want to try refinish it with Rustoleum high temp, how well will it work?

Depends in how well you prep the surface no traces of oil or grease

give it a shot of oil , let it sit a few, then wipe. You might bring the finish out by doing so. Years ago a lot of upper receivers had the purplish tint, soaking it in oil brought the blackish color out, sometimes.

I've already tried oiling it, but after a day or so it turn back into purple again.

If it was steel I would say dip it in som black ox solution,but I don't think it would stick to aluminum.
Try spraying it down with oil and put a blow dryer on it to see if it would seal it some how.Worth a try..

I used Rustoleum on my barrel stove and it is very soft paint that scratches easily. If you used the same stuff, I'd expect you to be disappointed with the result after the very first range trip.
That's just my experience though.

Instead of rustoleum you can use Alumihyde2 from Brownells.

I use it on my AK's and holds up real well.

AlumaHyde works well, as noted prep is everything, if you can sandblast it that would be great.
Multiple light coats with about 5 minute flash time between coats. The longer you can let it cure the before handling the better.

How does it fair against solvents?

Really well for me.And I abuse the snot out of mine.Although I wouldn't go using brake clean on it but it holds up to just about everything else.
The trick is to bake it in the oven at 200 for 3hrs or so then let it cool down on its own
Comes out tough as nails :)
