Protecting polished aluminum parts

[mech393]

ive used the por15 glissen on a chrome timing chain cover on my 454 , that's been around 4 years its still glossy but I put it on with a brush it was pretty thick stuff and it is hard stuff but I don't remember reading that it breaks down in sun light like the por15 black.

I used Cerakote Titanium on my new Doug's Headers for my 57. Came out great, just sprayed with HVLP after blasting with aluminum oxide (gives a good "tooth" compared to glass beads}. I did the inside (flow coated) as well. Material cost was $61 compared to Jet Hot $340 est for outside only plus shipping both ways. If you want the polished look, you need a big tumbler that I didn't choose.
