Selecting a roof coating brand

Question

Good morning to all, I am trying to keep everything in good shape on my 5'r. I re-coated the roof three years ago with liquid rubber brand material. The first full year everything looked and stayed great. During the second year small gray-black spotting started to appear and after uncovering for this year I couldn't take seeing more little black spots. I planned anyway on replacing all the plastic sewer vents (the 5'r is a 2008 and the plastic sewer vents were cracking and looking ratty). Finished that in May and was very pleased with the outcome but decided let's do the roof as well. To that end I decided to try the "Inland Coating RC-2000" product. I ordered 5 gallons directly from the company on June 2nd and looked forward to getting the job done before the heat of summer. First, the company was easy to deal with, BUT the shipping became a nightmare as the product tracked in shipping via UPS to Easton PA by June 4th and then disappeared. After GREAT frustration with UPS and a ton of emails and calls to both UPS and Inland C with NO resolve, I finally gave up on that and asked my Credit Card Company to intercede and cancel. I am gun shy reordering from Inland. So to the point I am now considering ordering the Hang's product from Amazon and would respect any input regarding Hang's (or other product option)before I order. SORRY TO POST A LONG STORY. Travel Safe and thanks in advance.

Here in the desert southwest we apply rubberized roof coatings to the flat roofs of our homes. Trailer roofs are also made of rubber. Many here have used their home's roof coating on their trailers with success. I don't know if you have any of that available at your Home Depot but it seems to work well.

From reading the information on the Heng's can that I ordered, it don't even mention appling it over rubber roofs. So I chose nut to use there product. The RV tech the I called requmented a product one can buy from Home Depot. He said he's been using it for years with no problems. If your thinking about using a vinyl base product, don't. The stuff on my roof cracked all over and had to be scraped off by hand. and it took them days (2 hours a day) to get it all off. I'm thinking he refured to as being silicone base product that whole better on top of rubber roofs.

I used Heng's Rubber Roof Coating on our 96 Southwind a few years ago.
It is holding up well to our Pennsylvania winters and summers.
Heng's goes on easily, like paint and needs no primer.
I used 2 1/2 gallons to put two lights coats on 30' of roof.
I'll use Heng's again.

2008 5er that saw lots of Az. sun. The prep work is paramount before any coating! Pressure washing, lots of scrubbing with scotch pad/tsp, recaulking, etertabond seams and Henry 587 and I dare anything to leak! While doing so much on the roof work, I also did extensive AC work and made a serious improvement in the cooling... cleaning the coils, insulating the return plenum and 6" step down ceiling diffusers.
