Maybe a low powered electric rig would be OK though.
I didnt use the strongest tip, like the one that will remove concrete and it was a 2500 psi unit. It did not do any damage and it turned out great. It turned an 8 hour job into about 2 hours. Like anything, if you aren't careful then damage will occur. Good luck!

Fiberglass Roof Clean and Seal

Tonight made some good progress. Mixed a strong batch of ZEP Floor stripper spritz an area let it sit 8-10 minutes. Use a small stiff brush and work the solution in more. Then add some Bar Keepers Friend and continue scrubbing removing the black streaks and additional coating. When finished wipe off and rinse with soapy water. I worked small sections and used lots of paper towels to avoid anything going over the sides. About 2/3 of the roof is complete another 10-12 feet to go.

I have come to the conclusion that my roof was coated at some point with a floor wax, then re coated over top of dirt and oxidized finish. I had areas that would not come clean with regular scrubbing, after removing the first coat of finish I was able to get rid of the dirty areas.

Even after I get done with this process there will be some additional wiping down with solvent to remove the heavy buildup in some areas. The floor stripper is not touching those areas.

I am now considering this project to be a roof restoration project and not a simple clean and seal!

Fiberglass Roof Clean and Seal

I had planned on using ZEP, even purchased a gallon but decided to wait and just go with wax for now. After dealing with the floor wax finishes previously applied I am not ready to put it back on. I may change my mind after waxing a couple times.

Not sure how a fresh properly applied ZEP roof feels like but my roof prior to stripping and cleaning was rough. Was not the nice smooth finish normally associated with fiberglass. After I stripped the finish and have it clean the surface is nice and smooth. My thinking the smoother the better and a little wax on top will shed dirt easier. The rough finish had dirt and grime in all the small imperfections.

I hope the ZEP holds up well for you. Be sure to report back next spring on the results.

Thank you! I hope it hold up also as my knee's are killing me! My roof was just starting to chalk a bit....is the reason I did it, I cleaned it really good before applying the Zep, the roof shines and looks just like the sides of the Coach now and very smooth. We will see how it holds up to Father Time? It is stored indoors when not in use......so it spends a large amount of time inside.

Finally got a break in the weather and had some free time to finish removing the ZEP mess from my roof. Took about an hour to do the last 8-10' of roof. Finally got my cleaning formula down.
1 part ZEP stripper, 2 parts water,
Use spray bottle and coat an area let sit 5 minutes
Sprinkle some BKF then scrub with stiff brush.
Let soak more adding more stripper if starting to dry.
Wipe off with paper towels, takes many and avoids getting stripper on side of MH.
Rinse with soap from bucket, wipe again with paper towels.

This process went quick on the last section and now the roof is starting to look like new fiberglass roof.

Next I will give the roof a good cleaning with soap and water then add some wax. Hoping to get this done done before we head out of town.

Here is the last section soaking.

So glad to have the old finish off and now can keep it looking good with regular waxing!

Does the Satellite TV Dome interfer with reception of your Jack Antenna mounted in front of the dome?

I would need/want to use a similar mount location.

Not that I have noticed. Majority of TV viewing is satellite though.

Won't the 303 keep the wax from adhering well? I think 303 is supposed to be reapplied every 4-5 weeks and I would worry the wax will degrade as the 303 does.

I expect the 303 will be gone when I get ready to wax. Will give the roof a good wash then wax. This will be a car wax and not any of the floor wax finishes.

One caution before you do seal it. Use DI COR for all you seams. It is a self leaving compound you can apply with a caulking gun. I just recently sealed a new front room vent I installed and went around on some of the other seams. It seals beautifully. About $7-$8 a tube. Well worth it.

All of the current seams have eternabond tape. I have been inspecting and repairing all my other protrusions on a regular basis.
Just re-sealed the solar panel, stripped off all the old and dicor self leveling applied. The remaining penetrations all look good now. But when I see cracks they get fully stripped and re-sealed versus just adding another layer.
What I have found during the removal of old is that under the top layer the old caulk has dried out and deteriorated, so the looks are deceiving.
