EastwoodInternal Frame Coating Aerosol | Internal chassiss Frame Rust Remover | Rust Converter and Prevention Aerosol Spray Undercoating for Vehicles |14 Oz, Black

It covers good and the spray tube make it easy to get in tight places. I'm afraid to say it's a one time use. First off the spray tip kept clogging and since I can't see when it's working or not I ended up cutting the brass tip off. It still looks to cover well. The other issue I had was I left some in the can to spray another area the next day, the nozzle had completely hardened and the can was done. That was not really an issue but a leaning moment. If I buy again I'll make sure to use it all at once. The bottom line is the finished product appears to work great.

This is an excellent product for inside of frame and other inaccessible areas on your car or other metal item that needs rust protection. I coated the inside of my frame radiator support with this. 2 years later I soaked the part in muriatic acid for 24 hours and the inside was still coated with this (paint).

Great product

Product seems great but extension nozzle clogs up to easy.

On my 2012 mazda 3 i was able to do the rocker panels, bottoms of all 4 doors, and the hatch lid with one can. mazda had great access hole on rockers, i taped the 24 inch extension to a coat hanger and it worked fine. bottoms of doors used just the extension and worked out well for those areas, easy to use, minimal odor, time will tell if it works well

Excellent product even comes with a hose

I drilled holes in the bottom of my rockers and sprayed one full cam in each one to prevent rust put one inch plastic plugs back in. This stuff works amazing

Good product!
