It truley works will restore your RV or boat
By Ed D
I do car detailing and my cars have to look perfect new all the time. That has to go the same for my trailer. Got a used trailer inside was like new and I think this trailer sat unused for a few years in the sun.
Now I need to get the oxidation off this used trailer we just bought. I tried regular Mcquires for cars clearcoat cleaner compound on a 3000 rpm polishing wheel. Not good enough.I ordered through Amazon McGuires RV 3 step oxidation compound 49, polish and wax. Fiberglass is a tougher finish then clearcoat and this Oxidation compound is designed to cut through and really remove all the garbage and oxidation built on the finish. It restored my dull slightly off white finish back to bright white and very shiny. As well as me tired, But its well worth the effort. If you are taking on a whole boat or RV by the 3 step Rv kit for 25.00 on Amazon. I bought an extra bottle of 49 heavy duty because 1 16 oz bottle ran short.

WARNING!........Their is nothing that will work without the right tools, time, strenth and energy involved in taking on this big a surface on 29 ft Rv with slide outs. You need a polishing wheel ( Not an orbital buffer they are not powerfull at all. I tried the dual action kind they are easier to controll but I like the speed of reg car polisher and prefer the 10 lb 7 inch 3000 rpm wheel using McGuires medium cut rasberry colored foam pad. Made just for taking oxidation safely out of the fiberglass.
I started on the full molded fiberglass cap front. IT had a dull SATIN LIKE white finish on it very minimal shine. After applying the compound with 3000 rpm wheel, polish then wax which goes on easy and I did by hand. The compound is what does all the work to remove oxidation. Its as shiny as a new trailer or a new bathroom tub at Lowes.
LET ME TELL YOU THE SHINE JUST AFTER USING THE COMPOUND IS AMAZING! IT works as its advertised. Then you follow up with the polish on a rag and wipe it off right away. Polish takes off any film left by compound and adds oils back to finish. They have a pure wax.Once you complete the 3 steps you will be happy you put in the time. Its really new looking.
Its a extreamly hard job.Takes per side about 4 hrs but I have to stop because it will wear you out holding polisher tightly and letting wheel and compound do its job.Its a good workout. But the end results are well worth the time. My trailer had medium oxidation, but people who used it that claim they started with a chalky finish have had the same end results based on the reviews I read on Amazon.I AM sure with a BAD OXIDIZED chalky finish you will need to constantly clean the oxididation it removes off the pad.But years of not cleaning and waxing require the pain staking process that goes along with removing all the dead finish to get down to fresh.
Tip.... For cleaning deep dirt on caulking I carefull use lacquire thinner on a small clean rag just folded to touch the caulking only. The thinner will melt the top layer of caulk every so slightly and remove the dirt instantly. Let it dry and then follow over the area with the wax, the wax will remove the film left behind and leave you trailer caulk look like new again. Dont effect the fiberglass Wont work if caulk is silicone.Try on small area to see results on you unit.

Please note.......... My trailer is 5 years old and though it was oxidized some but a dull shine was still appearant, I knew the gelcoat seemed still good. If your unit has been neglected for say 10 years or more it may be possible that the oxidation has gone beyond the Gelcoat finish which gives the fiberglass its shine. If so, You really have nothing to shine back up. 3 part restorer will remove the oxidation then the polish and wax will add oils back to finish but without the high gloss shine if the gelcoat is gone. Also the dullness may return as the oils dry out over the following weeks of months depending on fibergl ass gel coat in bad condition. But it has to be really bad looking and chalky to have killed gelcoat finish.
I would try a small section on an older unit and see if you get that desired shine before spending your efforts to restore the entire unit. If that is the case their are other polymer finishes that coat over the dead finish once you clear off dead oxidation and create a new shiny type coating that they claim will hold a nice shine back to old finish. I am sure you can see them on the net. People seem to like these products as well. I would only consider going that route if you indeed do not have a chance of restoring the gelcoat. At that point you have nothing to lose but you will have to reapply that polymer finish every year. But it seems easy as waxing the whole unit. But at least you still have an option.

A new units a lot of money a few days, a wheel, and this product on your unit can look great again.
Ill be done tomarrow,Been a long few da ys. Then cover this trailer up for the winter and know this will be the last time I will have to compound it due to how I take care of my stuff. Because its now going to be garage kept, covered washed and waxed as it should be. McGuiares products always do as they claim as long as your Gel coat is still their under oxidation. It cant bring a dead finish alive when its past that point. I love the results. Made me a tired but a very happy man. Why no voting buttons?

Worth it's weight in gold!
By K. Mutz
Used this stuff on a boat with heavy oxidation after trying almost everything else on the market to bring back the clear coat. This stuff is amazing. We used this on an older red colored boat and it looks almost new again. I highly recommend using this product.
