LOL !
This is known as " re sealing " the old , faded paint and yes , it works o.K. .
The tricky part is the partially flaked off clear coat .

I do not recommend this for a newer MH with a good finish, or with full body paint and/or clearcoat that still shines and still responds well to conventional waxes and polishes. This process is for older RVs that have lost their shine and no longer respond to wax.

I repeat: The prep-work is the most important part! Do not try to cut corners here. The cleaner your RV is, the better your final results will be.

Dip a white 3M scrubbie into water and then liberally sprinkle Bar Keeper's Friend (BKF) on it. Scrub the surface of the motorhome, rinsing the scrubbie and re-applying the BKF often. Do small areas at a time, rinsing well with water and a sponge as you go ( I used a "flow-thru" brush attached to a hose to rinse the BKF residue thoroughly).
>
> Step 3: Next you want to make sure that there is absolutely no remaining wax on the RV, since any residual wax can cause the Red Max to peel and flake. Mix up a bucket of TSP (1/2 cup) in water (2 gal), and use it to wash the entire RV again. You can use it with a carwash brush, a sponge, a pressure washer…anything you would normally use to wash your RV. Rinse well as you go, then rinse again and let it dry completely. You should now be left with a clean and smooth (although dull) wax-free surface. Congrats, the hard part is done!

> Step 4: Now comes the easy part. Shake the Red Max Pro (RMP) well, and pour some into a shallow container (a pie pan works well). Fold a microfiber rag to about hand-sized, dip it into the RMP (trust me, use gloves!), and squeeze out the excess. How much/how wet? You want it more than damp, but less than dripping. Now simply wipe down the surface of the RV with the wet microfiber rag. Don't try to apply a heavy coat or try to "rub it in"; just wet the surface (imagine wiping off a layer of dust with a damp rag). It really doesn't matter whether you wipe horizontally, vertically, or in circles, and don't worry about overlaps; RMP is very thin/watery and you are just trying to "moisten" the surface. Work your way all the way around the RV. The thin coat of RMP will dry very quickly; long before you've gone all the way around it will be dry and you can immediately start on the next coat.
>
> That first coat will likely look really bad; streaky, blotchy, shiny in some places, dull in others…don't panic. Each additional coat will start to even it out and build up a deep layer of shine. By coat 3, you will be grinning ear to ear. And coat 4 (or 5?) will be the icing on the cake. Not only will your RV shine like it hasn't shined in years, it will be a deeper color as well*. Even old, faded graphics will have a new lease on life! All for less than $30 total!

> *Note: This procedure will slightly change/darken the color/shade of your RV.

> Things (I learned) to keep in mind:
>
> -Don't use new colored microfiber rags until they have been laundered, as the color may bleed.
>
> -Don't try to "over-apply", or try for a heavy coat, or you will get runs. The thinner, the better. Remember, you're just trying to "moisten" the surface with each thin coat, nothing more. If you are getting a lot of runs, you're applying it too heavily.
>
> -Be careful around window frames, locks, latches, etc., as the RMP is very watery and will have a tendency to gather and cause runs. RMP dries fast, so keep an eye out for any runs and give them a quick wipe before they start to "set up".
>
> -Some older, deteriorated graphics may "bleed" color onto the rag and surrounding areas. If you notice any bleeding during the BKF or TSP stage (steps 2 and 3), then give a quick wipe of RMP across the graphics prior to step 4, which will seal them up. Then go ahead and apply the RMP to the entire RV (including the now sealed graphics) as per step 4 of the tutorial.

> -After each coat, go around and open/operate all hatches, locks, catches, etc. The RMP acrylic coating can sort of "glue" them closed.
>
> -You can also do the window frames (avoid the glass) and other painted metal areas; in fact, I did my entire Class C cab since, like the rest of my RV, it was also very weathered and dull. Came out great!

> Maintaining the Red Max Pro finish:
>
> Now that your RV looks like it has a new, clear coated paint job, you'll want to maintain that new finish as long as possible, right? Well, good news. With Red Max Pro, that's easy to do as well.
>
> Most commonly used car wash soaps and mild detergents will not harm the Red Max Pro finish, so you can wash your RV as you always have. In fact, you'll probably find that it comes clean much easier than before, as dirt, bugs, and debris seems to "float" right off quite easily. You do want to avoid anything with Ammonia in it, such as some window cleaners, since ammonia will remove the Red Max Pro (think "floor stripper"). The tire cleaner spray at coin-op carwashes has also been shown to remove RMP. Minor scratches or blemishes in the RMP finish can be touched up easily with a quick coat or two of RMP. Do not apply wax, as wax will interfere with any "touch-up" coats of Red Max Pro later on down the road, causing them to peel or flake.
>
> And after 6 months to a year, if the finish starts to lose it's shine, just give the RV a good wash job, let dry completely, and then give the RV a quick touch-up coat or two of RMP, wiping it on just as you did originally.

> Disclaimer: This procedure worked wonders on my weathered, oxidized RV, using the products and steps listed above, and I have no regrets. Hundreds, if not thousands, of others have also used RMP with similar results. A very few reports have surfaced claiming "yellowing" or "peeling", but most, if not all, of those have been attributed to improper surface prep. However, these products are admittedly not designed or marketed for use on the exterior of RVs, and I make no warranty regarding their use or the long-term effects on your RV. Use at your own risk.
>
> A few final notes:
>
> Some people have voiced concerns about the chemicals used in the prep stages. Bar Keeper's Friend (BKF) is similar to scouring powder, but much less abrasive. In fact, it is made for cleaning and polishing fiberglass. Used with the fine white 3M scouring pads, it is excellent for removing stains, oxidation, and chalkiness from fiberglass gelcoat without scratching.
>
> Trisodium Phosphate (TSP) is indeed a very strong cleaner. While it works very well to remove wax from the RV, it can burn if mixed too strong or left on your skin too long. If you are not comfortable with the TSP, some have reported good luck using Dawn dish soap to remove the wax.
>
> Ultimately, neither of these products (BKF, TSP) are required. What is required is to remove all stains, soiling, oxidation, chalkiness, and waxfrom the surface of your RV prior to applying Red Max Pro. Whatever methods you are comfortable with are fine, as long as they accomplish that.
>
>
> If your RV still looks good, and still shines...then use a good quality wax. But if your RV has deteriorated and you are looking for a way to breathe new life into it, RMP is an option for you. Go ahead, Google it. Read up on it. Read about those who have actually used it. Then make your decision.
