Solvent Review

I use the solvent to thin the Por-15 paint so I can spray on a car frame. Also to clean paint brushes when applying Por-15 with a brush. Need it to clean paint from my hands.

Donald Robinson
Great solvent

Easily cleans off paint.

Peter Reichert
Best paint for rust

Ive been using POR-15 for over 15 years, on car restorations. Ive tried other products claiming to do the same rust control, POR-15 IS THE BEST. Its easy to apply, brush or spray, self leveling, & durable.

Works pretty good

Works good to clean rim of can and splatters, but don’t get the POR-15 on your hands. Even after cleaning with the solvent it takes days to fade away

Tim McCartney

I did a 4:1 mix and it worked great for me

Add POR-15 Solvent gradually per coating instructions and stir thoroughly until desired consistency is obtained. 

Cleaning Brushes and Rollers: Agitate brush or roller in product until all residue is dissolved. Press out excess, wipe with a clean towel, and lay flat to dry.
