Yes, it's "rubberized" so it's flexible. This one doesn't say "automotive" but you find it in the automotive section of the store. The only problem is that if you put it on to heavy it foams up so it's hard to get a good smooth finish.

I'm a blacksmith. Black is a usual color for ironwork, but, I hate gloss black finishes. Flat black paint has marble dust added to take the gloss out. That dust wicks moisture through to rust the metal. If you want a flat black finish you have to put a primer on first, and I haven't been impressed with primers for blocking rust either. This stuff is a whole different formula, it's made to be a rust protector. I went to a wax finish for my ironwork, long ago, because paint just isn't durable, and it's hard to refinish. Since I found this stuff hiding over in the automotive section I've been using it for tooling and equipment, in the shop, that I want to keep from rusting. It's not as tough as paint but it blocks rust better.
