As a recap, I put together kind of a "tutorial" on this process. Here it is:
Restoring the finish of an older motorhome using Red Max Pro (#3):
Materials:
-Red Max Pro (Step 3) Low Maintenance Floor Finish (available at Lowes)
-Bar Keeper’s Friend (powdered)
-TSP (powdered)
-White Microfiber rags
-3M scrubbies (white)
-Latex gloves
Preparing the surface is the most important part, since anything left on the surface will be sealed under the Red Max Pro acrylic coating. Start by washing your motorhome as you normally would, making sure to include the roof, rinsing well from the top down.
Now, you want to remove any and all stains, soiling, oxidation, and chalkiness from the surface of the motorhome. Dip a white 3M scrubbie into water and then sprinkle Bar Keeper’s Friend 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.
The next step is to make sure that there is absolutely no remaining wax on the motorhome. Mix up a bucket of TSP (1/2 cup) in water (2 gal), and wash the entire motorhome. You can use a carwash brush, a sponge, a pressure washer…anything you would normally use. Rinse well, and let the motorhome dry completely. Congrats, the prep-work is now complete!
Now for the easy part. Pour some Red Max Pro (RMP) into a shallow container (a pie pan works well). Fold a microfiber rag to about hand-sized, dip 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 motorhome with the wet rag. Don’t try to over-apply; just wet the surface (imagine wiping a layer of dust off with a wet rag). Work your way all the way around the motorhome. RMP will dry quickly; by the time 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, shiny in some places, dull in others…don’t panic. Each additional coat will even it out and start to build up a deep layer of shine. By coat 3, you will be grinning ear to ear. And coat 4 will be the icing on the cake.
Things (I learned) to keep in mind:
-Be careful around window frames, locks, latches, etc., as the RMP will have a tendency to gather and cause runs. Watch for runs and give them a quick wipe before they start to “set up”.
-Watch for “bleeding” of color from older deteriorated graphics onto the rag. This should only occur with the first coat, as the RMP will then “seal” them up. Subsequent coats will not have the problem.
-After each coat, go around and open/operate all hatches, locks, catches, etc. The acrylic (RMP) coating will sort of “glue” them closed.
You are the best! Thank you for the step by step process, this rookie is looking forward to starting our 37ft MH. Is better to do the front and rear caps and then do one side and jump to the other? I was just considering from others it's best not to do it in the heat of day or direct hot sunshine?
