Best to apply with a brush that can be thrown away afterwards. Not good in a spray gun (will ruin it for good). Wear OLD clothes and DO NOT get on your skin as it will not clean off. Very tough finish if used properly. I used a rust converter as a primer and then coated over that. Be sure to clean off loose rust before any application of any product. The coating is a tough as any epoxy and maybe even better. Be sure to put cling wrap over can to close it up so the metal top does not contact the metal can. If you don't use the cling wrap, the can will never open again. Review: Compare against Por-15 - I bought the black Rust Seal for my snowblower and used Por 15 for the orange part. This product is much better than Por 15 - the next day is was hard and I could sand it and apply a second coat. It is a true moisture cure urethane. 2 days later and I can’t touch the orange.
