Protecting sand blasted intake????
My aluminum was looking bad, so I sand blasted it with aluminum oxide blast media. It look great right now ,but I know the finish will get dull. I was going to use a walnut shell media next to see how good it l looked. Does anyone have an idea on how to protect the finish on this intake? I have used a clear polurethane from Eastwood, but I did not like the results after a couple of months. Maybe power coating is the answer.
Thanks
Tony
