Great for RV and boat
This stuff is amazing! My husband uses this on the boat and RV. Our RV is orange and was heavy oxidized. This brought the color back!

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.
