I have read the instructions on the dicor products and it says i need to hang plastic all around the damn MH. Well i don't have any. My question is with a MH which is not painted, just white fiberglass with a gel coat is that really necessary or does it just effect paint and decals. I do have some decals but not many

I just use a mild detergent when cleaning the rubber roof and then immediately follow that up with a complete washing of the MH. The cleaning of the roof will streak murky white waste water all down the sides of the MH. Pay special attention to the roof channel drain spout areas.

Last year I decided to recoat my roof with this system. Per the Dicor instructions I covered my RV with plastic sheets from front to back (a BIG job). I used the best painting/masking tape I could find. Then I used the Dicor roof cleaner. Guess what, it caused the masking tap to come off the MH. By the time I noticed it, the cleaner had put streaks all over one side of my fiberglass MH (not painted). I immediately washed the whole RV. However, the streaks did not come off. I ended up having to use a buffer with buffing compound to get the streaks out. It even left nasty white stains on my tires.

Whatever you do, be very careful with this cleaner. It really does not like fiberglass.

What you doing sounds like a lot of labor and troublesome.

You have a 99 Allegro. The roof is old. If you plan to keep the RV another 10 years, why not use EPDM Liquid Rubber and coat your roof DIY. No special roof cleaning products required. NO primers are required and ONLY one coat is needed.

It is self leveling, resists UV rays and covers the roof like a giant blanket. I put it on my RV and it is great.

Time is money and so is the continual annual and semi-annual purchases and use of special cleaning products, along with the removing and re-applying calking along roof seams, vents, and mounted roof accessories which attracks dirt and is always cracking.

The crud you wash off the roof makes a mess of the sides, but if you wash the sidewalls immediately after the roof, then no worries. IMO taping sheets of plastic onto the sides is far more work than washing afterwards, and you probably were going tow ash the sides anyway. Just don't delay - wash that crud off immediately, not a day or two later.

But if you want to use the plastic, you can buy inexpensive plastic painter's drop cloths at Lowes, Depot or Walmart. And get plenty of masking tape too.

When I wash the RV roof, while I'm washing, DW is on the ground with a 2nd hose rinsing the sides of crud off the roof. I use SpicNSpan or Dirtex cleaner.

Dawn dish soap twice a year, roof first then sides. No harsh cleaners on mine. If you have to tape off with plastic to protect the sides I'd worry about the strength of that stuff eating off the finish. JM2C

I wonder if there is a side by side analysis of EPDM & Dicor. I'm planning in doing mine soon. Price looks to be about the same.

Let us know of your findings.

I would compare: square foot area coverage per gallon, Cost per gallon & 5gallon, Apply directly from can or mix catalyst, Water base or not, Number of coats needed in application (Labor), is primer needed, Thickness (mills) of coating when dry, Recommended drying time per coat, Self Leveling or not, Colors available, Ease/difficulty of application, UV resistant, Anti-chalking. Products needed for washing, warrantee. what kind of roof prep is required prior to application, What industries and businesses use the product. Is shipping free?

well you didn't say if you wrapped it up in plastic, or did you just rinse off the sides, or did you even use the cleaner????

After reviewing Dicor information, Dicor is available in EPDM for rubber roofs.
I'm looking at the Dicor Cool Coat for my rig.
Hoping to get it on before I head South for vacation.

Real happy with the Dicor I put on my rubber roof. Looks brand new. Not really sure how much the ceramic chips add to the reduction of heat transfer but we were on St George Island last week of July with temps up to 95 and heat index of 112 and our Tiffin Allegro with one A/C kept us more than comfortable. The boys even used sleeping bags at night.
Three Coates on 32' rig equaled 1 1/2" gallons of Dicor used. Great product.

Oh yea, taping plastic around RV was a waste of time. Activator pealed tape off in about 1 minute. I would skip that step next time.
