COLLINITE 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)

Great product. Removed black streaks form dock rack quickly.

Works great

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.

Awesome cleaner for fiberglass

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

There’s nothing easy about buffing and polishing but this product actually works as well as it claims. I did use rubbing compound first on some heavily oxidized areas then went over the whole boat with collinite 920. I ended up with a beautiful reflective shine. And I did it all by hand (I leave the power buffing to the professionals). Sealed it all up with Challenger boat, RV & aircraft wax and my boat looks beautiful again.

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

The product itself worked verry well, even on the bottom with stains and some scum line. With a buffer it cleaned it very well and ready for wax. I did find it very difficult to wipe. It would dry very fast and if I wasn't fast enough I would hhave to re-wet with product to clean off. My BIGGEST COMPLAINT was the screw top bottle. 1st day I got so aggrivated trying to put a small amount on the buffer wheel or applicator pad. I kept getting too much, note nough, and then screw the cap on and off. The second day I I brought an empty body lotion bottle with a pump and poured the Collnite in it and then it was so easy. The should have at least put a cap that had a small discharge port on top.

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.
