So i just started my go at cerakoting.

 

I blasted my first lower with 120 grit aluminum oxide.

It came out much better then i thought it would but me thinks i may have blasted to much. Anyone cerakote have any advice? good bad? less more?

I have multi-regional earth/ oven cure in the mail.

Reblast it. Experiment with lower pressures.

Reblast?

 

I was at 100psi, I'll drop it down to 80 and see what happens for the upper. Im also using the smallest diameter blasting nozzle, so i can play around with larger ones.

 

I was really under the impression i wasn't going to get anywhere near these results, abrasion wise, and it cut right through the anodizing before i realized it. My set up is definitely less than ideal with 5.3cfm at 90psi, but it's getting the job done.

lol, you quoted me as I fixed it.

100 is too high. Mess with it between 40-50 or so. Use a med size. Min 6-8 inches away and keep it moving.

OK, I probably should have started on the low end, but i figured to just max out what Cerakote recommended.

 

Should i leave some of the anodizing on? Something that has been very unclear to me is when exactly i have the finish i'm looking for.

Can't answer that. I've only blasted glass, (made a cool wine glass for wife), and stainless steal. Actually got ballzy and blasted my new Stainless Kimber Raptor.

I do know that you should always start low because you can't get back what you remove. I guess in your case is get the finish you want and get it even, then do your coating. Do some googling beading. I did a bunch of research before I got crazy.

I've never cerakoted before so.....

Different metals get different pressures. Aluminum is soft and should be done low at under 30 PSI.  I think your done by the picture. Degrease, heat,  and get ready to spray, inside first, outside last.  It will turn out fine. If the oxide is done right it does not take much to rough up the surface to get it ready,  Waiting on color samples getting ready to redo a few,

When I do the upper tomorrow ill drop the pressure down to 30psi and see the kinda finish it gives me. No wonder the anodizing melted off.
