Used this stuff in anger on a 22year old Subaru. Blast cleaned everything first then laid it on with gun supplied and brush. Fumes are really serious even from the open tin let alone vapor from spray. You NEED a good quality respirator and overalls. Stuff needs time to cure before you run the engine or any demisters as the fumes will contaminate EVERYTHING! IT WORKS! I've tried other stuff over the decades, this is the ONLY coating that actually withstands punishment from a tough environment. The fact that you can see through it means it can't fool you into a false sense of security - like Waxoil does! Stone chips in the wheel arches will knock it off though so will be re-coating and bed liner top coating the arches before Autumn. Been brushing Buzz-UP onto all metal items since - bench vice, trailer frame & hitch, granddad's bike and next doors cats and dogs etc. RECOMMENDED!
Iíve used a few different cavity paints over the years , this is by far the best Easy to apply with excellent results I can sleep With ease knowing that I have protected the chassis with the best possible product !
