920 Cleaner-Marine/RV Stain, Water Spot & Oxidation Remover. Easy to Use Heavy Duty Cleaning Compound Restores Shine/Enhances Look. Preps Surface Fast for Wax Protection. (16 fl oz)

I used the 920 on my 23ft boat. It goes on easily and cleans well, but it almost took the whole bottle to complete the job. I did the whole boat including the inside and hull so you can guage the amount you'll need. I do wish the co.pany would modidy the bottle so you could just squirt it onto a pad, rather than take the top off. Also Make sure you tape off any rubber or sensitive items as it will stain them white (see photo). I recommend this product. I also bought the 925 polish that I will use next.

Best stuff there is. I use to clean the hull followed by an application or two of 925. This will remove minor flaws, spots, etc. I use a cheap, synthetic wool hand mitt for difficult to reach areas with little effort and a wool pad/drill adaptor for coverage areas. My gelcoat is black and it cleans and restores it to showroom quality. Worth every penny.

Awesome cleaner for fiberglass

This is the easiest wax ever, just wipe on, wipe off. A quick buff with my buffer leaves a deep shine. It works fine in cool weather but it is a little thick coming out of the bottle until the temperature warms up to 70 degrees.

Works well. Easy to use, apply and wipe off.

Maybe just me but get great results using the 920 cleaner first followed by the 870 wax

I love collinite cleaner and paste wax. I use it every year and our 42 year old gelcoat sparkles.

I was disappointed in the 920 cleaner. I used it with a DA polisher, with wool and sponge applicator pads. My boat had some mild oxidation and I was very disappointed. I applied on cloud day with temperature around 63. The 920 dried fast and was difficult to remove. I had high expectations based on the reviews.

Esperaba que fuera muy bueno para la limpieza de la fibra de vidrio de mi lancha :( En realidad no tiene nada de especial como dice en su publicidad ... seguí las instrucciones de la etiqueta pero me desepciono mucho sus nulos resultados .... no lo compro de nuevo ni lo recomiendo para quitar manchas de agua en fibra de vidrio

One bottle did the entire hull of my 38ft sailboat and the results were great! I have already purchased another bottle!

Xcellent stuff

Expensive stuff but cleaned most the powdery surface from the front of my caravan, leaving a surface that could be polished to protect it from the elements.
