Good quality primer for automotive
Best primer money can buy. It adheres to my 57 ford f250 body and allows for automotive paint to stick. I have tried the rustolum brand which caused the automotive paint to peel. If you’re doing a restoration, use this as it also has filler in the primer.

Nozzle Clogs
This product is great, there was a branding update that changed the nozzle making it clog up after 5 seconds of use.

Paint wrinkled on me and I don't know why. Have to return
I prep the area clean and paint goes on fine, but within 10min the paint wrinkled in areas. Will have to sand off and start over with different brand
