### ⭐⭐⭐⭐⭐ Review
*by B***R on 2 October 2024*

I'm quite impressed with this, enough so to follow this can with a case of 12. Goes on marginally prepared surfaces quite well and has a nice sheen to it. Goes right where you aim it and no overspray to speak of. Dries well and relatively quick. I sprayed the trunk of my 1947 Ford as well as under the fenders after basically just vacuuming the surfaces and wiping obvious messes up. I will try to update this after some months have passed of usage.
