They were sand blasted. They now have a slightly rough finish. Should look great with some flat black Rustoleum High Heat flat black.
I have a question. What is the best way to keep the bare aluminum from oxidizing over the next few months. Would wiping them down with some vegetable oil help?? The will be stored inside my shed, so I don't know if they will be prone to any oxidation or not.
OK, I know that if ground down a box clean and left it outside, it would oxidize pretty bad. I did not know if it would do that inside if it didn't get rained or condensation.
This. ��. ��
You can put them in my basement!
