Deep shine
Best product for gel coat RVs and boats. Due to a drought, I must wash my RV at an 18-wheeler wash, but after that, I polish and wax the RV with Meguiar products. I repeat this process annually. The RV is six years old, but looks brand new. I highly recommend Meguiar’s products.

Best final polish before wax or ceramic coating.
I used this polish for decades and it always gives excellent results as the final polish before waxing or ceramic coating. It works ell with dark or light colors. It gets out the final micro scratches that other polishes do not eliminate. I ordered from Amazon this time because I could no longer find it locally.

Good for light oxidation
Actually worked great on an old boat which was losing the gelcoat from decades in the sun. You could for example wipe the blue stripe and have a chalky blue on your hand. Put some life back in. And cleaned up very nice with a Kraftpaket polisher. Highly recommend using a polishing machine and getting quality polishing sponges to save yourself a lot of work. Afterword I put a modern ceramic coat to seal it and protect from further sun damage. Came out far better than expected! The blue stripe looks like new and I got a lot of compliments in the marina. I had some left over so one bottle will easily do a 10 meter sailboat. Great value for the difference it made.

Effective Boat Motor Cleaner for a Fresh Look
I recently tried this boat motor cleaner after neglecting my motors for a couple of years, and I was amazed by the results. Despite being a bit pricey and requiring a generous amount for both my main motor and kicker, the cleaner worked wonders. Unlike other products I've used before, this one successfully removed tough water spots and hard water build-up from the bottom drive unit. Although it required some effort to scrub, the outcome was worth it. I highly recommend this cleaner for anyone struggling with stubborn stains on their boat motors. It's truly a game-changer that outperformed all my previous attempts combined.

Second step in restoring my RVs oxidized fiberglass finish - EXCELLENT results
I'm posting the same two photos as I did for the oxidation remover, the photo delineated with green dots, shows my oxidized fiberglass before using the fist step Meguiar's Marine/RV Heavy Duty Oxidation Remover. The second photo shows the results after using this polish. I could have kept going but was happy enough with these results. Great products. Do them in small sections for best results as you need to get it wiped off before it dries too much.

Wrong product for vehicles.
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.

I hand polished my boat with it and it looks shiny and new again, very impressive! It even fixed a few scrapes and marks that I thought were permanent.
