I know this thread is almost a year old...but I've been searching for a solution.
My Weber Genesis Silver B has the paint coming off the inside. I stopped cooking on it when it started peeling, didn't think that would taste too good :)
Question is, what do I sandblast it with? I have high-temp paint, but I want to clean it up first. The outside is fine; just the inside, from blasting the grill with high heat and then dropping right before steaks go on (to get a nice char and cook to med. rare).
I thought about black walnut shells, but will that be strong enough? Just don't want to spend alot for material, my buddy has a blaster kit I just have to provide the abrasive.
Thanks in advance,
