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.

Use in my shop all the time for small areas equals no waste

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
