Easy to use..great results!
This product actually delivers on its promises! It took of years worth of road film and grime from our motorhome..leaving a clean base for the application of Poli Glow polish... Our motorhome is now looking shiney and new again. Very easy to use..just mop it on..let set for a few minutes then pressure wash off.
