Meguiar's® M4916 Marine/RV Heavy Duty Oxidation Remover - 16 oz.

Amazing product! Only took one time using this and many years of oxidation came right off my boat. It looks almost good enough to not have to wax it, but will with Meguiars boat wax, which is just as good.

I bought this to take oxidation off my camper tried a lot of different stuff and it's the best I found Thales it off and shines good a lot of work but it works great.

This product does exactly what it claims it will do. It will clean the oxidation off of fiberglass but this is not a piece of cake job when you start this job you have to have the muscle to put behind it; it requires dedication and follow through; it's a 3 step process from the remover to polish to wax. It takes all three to do the job.

We hace a 4 year old travel trailer with tan gel coat fiberglass finish that sat in the Texas sun and paid $$ for a highly recommended detailer who specializes in RVs. Took him 8 hours and barely looked "better". While researching better options, I came across Meguiars Oxidation remover. An hour with it and a rotary polisher and the section we did looked like new! Stock up on this and some good polishing pads and your money will be well spent! In the picture, we polished the left front. You can see the chalky oxidation of the untouched sections. You can also see the reflection of trees in the polished section....no wax yet applied! Two thumbs up!

I trust Meguiar's products and this is no exception. This is for use on a jon boat and a pontoon. It's a good product at a good price.

My daughter was getting married and wanted to use my Dad's 3 Chevy to drive away from the wedding. It had been heavily oxidized for years! I bought this product and my brother used it on the 53 for me. When he drove it into my driveway, I was so profoundly astonished at how wonderful the pickup looked! I hadn't seen it look that good in so long!! I was thrilled! He said it did not require a lot of elbow grease either, which made him happy! I ordered him some the next day!

great product took off heavy oxidation

49 does a great job with bringing back a deep shine to a previously maintained gelcoat, without going through the hassle of a complete compound.

I've used several Meguir's cleaning and polishing products 9n my vehicle. And this is not different, leaves the RV looking great.

product didn't do what it says it does
