I used the alumahyde on a 1911 that I built, just as a finish until I get more rounds through it and decide on an actual finish. I am pretty disappointed in it. I read the directions, watched the video and followed the steps that are supposed to be done (basically the same thing you described) and and let it cure for two weeks. After all the time and effort it is quickly wearing on all contact areas with my holster and where the slide makes minor contact with the frame. It is no big deal to me as I really dont care what it looks like but I really did expect a little more from the product. I have stuff that is Kryloned that has lasted longer for a lot less money. I know a lot of people have used alumahyde and not had any problems with it but the 1911 will probably have a new park finish and everything else will get krylon rattle can.
I will admit to this though, the frame did already have a good park finish and it is holding up alright.
YMMV

as for the gunkote. so far so good it's still going strong after a year. media blast with alum oxide 120. thinner to degrease it. used a badger 150 airbrush to apply it. very flat too. but if you don't media blast it. it will turn in shiny. and you'll have to start all over again.
