I was a bit skeptical to start. This made me a beliver. Very little work, easy cleanup, follow it with a spray wax and it looks like a million bucks.

My car is almost 20 years old and the age is becoming increasingly noticeable in the paint. Many water spots are so old that they’re permanent, but this product did a good job of removing most of them after laying on this stuff heavy on the hood of the car, letting rest for a few minutes, then wiping down with microfiber.

This works really well. It helps get rid of any scratches in your car and it shines it. It wont work for deeper cuts.

I was doubtful that this product would work any better than the regular one but it really was different. Used on a 2004 Fiberglass class B motorhome and it really shined up the dull surface. I think when I do more coats it will even look better. Very pleased.

This stuff says it's for fiberglass and gel coat. I wouldn't recommend using this stuff on a automobile as I have read that others have used on their automobiles with bad results. Use the meguiar products made for automobiles. And for dull fiberglass or the gel coat. I highly recommend buffing first before applying the polish. I've tried applying this to a faded gel coat/fiberglass. It will absorb it up. It will work good on a new gel coat/ fiberglass boat RV ect.

The product works great. However in applying this product you must do small sections at a time approx. 2'x2' sections in the shade. It can be hard to remove. You may need a spray bottle to apply a light mist to help with removal. I DIDD NOT APPLY THIS TO A BOAT it was used on my vehicle. I DO NOT KNOW HOW THIS APPLIES TO A BOAT HULL OR FIBERGLASS.
