I have a photo of the after effects:
I also agree that a sand blaster is a good friend. Mine does a great job but is pretty flaky and hard to get in touch with.
For me personally I like to do as much of the work as I can myself. I don't mind getting dirty though and I enjoy the process of being able to restore these old grills from start to finish myself.
I can definitely see the advantages to blasting and can totally understand why a person would go that route.Josh,
I admire your do-it-yourself style. I feel that way sometimes, but I am getting old enough that I am also OK with farming out to a sand blaster. Another consideration is how you like the significantly different looks you get from the two processes. Sand blasting almost always comes out with a uniform look. The cast aluminum takes on a bit of a dull grayer look, vs. the shiny aluminum that a grinder/cup brush gives. The wire brush look can give different reflections depending on your viewing angle. You also have to do - as I believe you do - and go the extra 2 or more miles to get to some tight spaces or still have a few black carbon stains remaining.
Either way, you are going to get a grill WAY NICER than any of typical postings of used grills - even ones where the seller claims to have cleaned them well.
