Meguiar's M77132 Heavy Oxidation Scrub

Good for detailing rv or boats. Even some type of work vans

I used this on my 94 Ranger Bass boat that hasn't had some tlc in a few years and Holy crap the oxidation just goes away without having to buff or sand the gelcoat. Definitely will be buying a bigger bottle of it in the future.

I wished I had taken before and after pics. My camper had been neglected and it DEFINITELY helped save hours and hours of WORK!!! Well worth the cost. Save yourself ALOT of work and get this before you start buffing!!!!!!

Just another mediocre oxidation remover.I have a 16 year old diesel pusher coach that lives in a climate controlled garage when were not on the road.It's exterior is all original and the white fiberglass gets cleaned and waxed about once a year on average.This year its been nearly 18 months since the last detail job and before we head out on this years adventures I wanted to give the coach a really good cleaning.I saw Meguiar's new Oxidation Scrub advertised online and since it was made by Meguiar's I bought a bottle to give it a try.This year the coaches gel coat was was starting to look a little oxidized with a touch of a yellow cast to anything reflected in the surface.Mind you this is not a heavily oxidized surface but a surface that is just a little cloudy when your up close. So I had thought that perhaps Meguiar's new Oxidation Scrub might make the job a little easier. So I tried the Scrub in several locations, one using a soft brush and the other using a soft scrub, both as recommended. The Results, both the scrub and the brush removed some of the yellow oxidation, but each left the surface somewhat cloudy with fine scratches... So it was a just a little whiter and brighter but nothing like I had hoped it would be.So it was back to what I have used before Meguiar's M4516 made by 3M or 3M branded 3M 39003 Finesse-it II.Using either product I was able to get the mirror like finish the coach had when new. Did several square feet with and with out using the Meguiar's Oxidation Scrub FIRST. And there was NO Difference in the end results except that using the Oxidation scrub took more time and was more work.Perhaps if you have heavy oxidation it might be of value, but with modest oxidation it was not useful at all.. Was really hoping that it would make the job easier but no such luck.. Now I have another bottle of useless stuff added to my collection to good to be true chemicals...

I have tried all manner of products (about 15 of them) for removing that chalky oxidation from an old (1988) boat. Not sure it was ever polished and waxed in its life. Most products don't work well. The few that did required a lot of elbow grease and or a machine and lots of time.This one does the trick... and easily. I received it and ran outside to try a spot. Using a kitchen sponge with a little plastic scrubber on one side... I put down a bead of product and scrubbed in little circles for no more than 30 seconds. Then rinsed. Not perfect, but 95% of the oxidation was gone! Another round with about 15 seconds of scrubbing and that section was free from oxidation. No more chalky mess!Hats off to Meguiar's!

I guess “heavy” oxidation is subject to interpretation.This product works pretty well on lightly or slightly oxidized fiberglass gelcoat, but not at all on heavily oxidized ( rough, porous, chalky) surfaces.Good for a little oxidation and deeper cleaning than a boat wash, but don’t expect miracles in a bottle.For “heavy” oxidation, get out the rubbing compound, buffer, scouring powder, or sandpaper!

Great product. Smells nice, don't have to use a mask, nor gloves. Goes on easily and a small amount goes quite a ways. Used it on our fiberglass travel trailer and wow! I did not realize how yellowed the trailer had gotten from old wax. It took the wax off easily, brightened the trailer to white again and took out all sorts of oil spots, road grime, diesel blow back -- things we were having trouble getting off the finish. There had been a decal that had fallen off and we could never remove the outline - but this product magically took the residue off in one application. I did go back and do the trailer a second time as I cld see areas that I had clearly missed. I applied it with a damp buffing pad (soft), hosed it off without letting it dry, then a microfiber towel to dry it. You can immediately feel and see the difference. I was hoping it would have brightened the colors of the decals ( gold, blue, and red) - and for whatever reason the blue had faded the worst and could not be brought back, although my husband said the red 'popped' right away. I've got wax (ProtectAll) coming via Amazon. The trailer looks great now and it's 10 years old, but the wax should certainly make it shine and will protect it from oxidation, UV rays, road grime. I used an amazingly small amount for two applications on a 30' travel trailer.

Tried several products for my 5th wheel which had a lot of oxidation. This was the easiest to use as the instructions call for brushing on and remove with clear water. Did much better then the other products I tried and was easier to apply and remove.
