I tried rubbing compound with little luck and I have used 800 grit sand paper, but he paper breaks down very quickly and I have to use an additional sheet. I think next, I will use a Scotch Brite pad and see what happens. The cap is at the point where I do not believe it can look an worse no matter what I do. I also live in Florida. Any other ideas?
Get a car wash brush with a long handle and 2 buckets. In one bucket pour about 3 inches of Zep stripper. In the other bucket just fill with warm water and vinegar.. And a microfibre mop.. Start at the BOTTOM! THIS IS IMPORTANT Do small sections at a time side to side then work your way up. First dip brush, apply to a 4x4 section. Rubbing in circular motions. Then do the same thing with the clear water and microfibre mop. Immediately rinse with a fairly good pressure hose. Repeat until done.
After this rewash the whole area with amonia and bleach mixture with some dawn dish soap. This may make some color bleed out of stripes. Don't be alarmed.
Now, after this, reapply the Zep high traffic floor sealer. 5 thin coats..
About now you're saying "are you crazy??!!". Maybe, but I've found the secret to touch up reapplication is once a year just wash with amonia, bleach, and vinegar. Then apply 2 coats. I don't know how often you wash your rv, but I use a waterless wash system unless I've been on the road and have built up dirt and grime. Then I use turtle wax
car wash with wax. Its easy, one step just rinse with water.
My MH is 15 years old. I have the whole thing done with Zep. The front and back caps are really the only areas I had to strip like this. I reapply 2 coats every year, its been 4 years now and I spend 5 months in the Southwest. That sun is even worse than Florida.
