Anyone used this stuff in the spray can? I know it can't be as durable as POR-15 or Rust Bullet, but being able to spray it is a huge plus. If it's decent, I'd consider hosing it all over the underbody and frame to maybe stop the rust and then hit it with regular spray paint. POR-15 is torture to paint with while laying on your back under a vehicle - gets on you, is permanent if it gets on the ground, etc. Plus it doesn't seem good to glue bolts down with it - but I've got no problem spray painting over all my bolt heads/threads, brake lines, etc... Anyway, if anyone has any experience with the stuff, I'd be real curious to hear.
