This stuff is great. It sticks to the surface. Its a hard protective coating. It scotch brites smooth. As long as UPS doesnt damage it coming to your house, you will love this stuff.

Product is amazing. Once cured it cannot be scratched or scraped off. Solvent resistant as I soaked my gun tips in lacquer thinner for a week and still had to scrub off dried primer (my fault as I should have cleaned the gun immediately) Original order damaged my UPS and received an email advising product was thrown away and shipper had been notified. Contacted customer service and Caroline looked up my order and immediately sent a replacement. Excellent customer service after the Sale!

I wouldn’t use anything else. 18 years ago I used this on my RV6 and on the exterior wet sanded with 600 grit and then PPG Concept top coats. That RV still looks great today. Now I’m using on my Xenos project. This is durable stuff.

This stuff is fantastic. I used PREKOTE to treat the surface and then spray the AkzoNobel. Easy to spray and mix. Drys hard as rock. Does not scratch or flake off.

Love this stuff but having to buy a gallon to get a quart is expensive and wasteful. So, I buy 8 quart containers and after thorough mixing of each gallon, I pour the contents into the quart cans and reseal with the hope that I can use it all up before it dries up! I was disappointed that the color was more of an olive drab instead of the bright green in the aerosol can, however.
