I am working on a 1968 prevost champion and need to get rid of the water leaks first. Roof first, windows next. Any suggestions as to what's the best covering to use to waterproof the roof? |

It depends on what you want to do and what kind of leaks you have.
I used a product called Cool Seal, its available from camping world. Down side is if you want to see the metal color of your roof, forget it, Cool seal is Bright White. I think it can be painted, read the label.
Cool seal is painted on with a roller like a thick latex paint and dries very pliable. It moves withthe body preventing leakage. If you have a location that has excessive movement or vibration, they have a cloth you use to saturate and apply on or around struts, vents etc. I applied this on my RV in 90 and it never leaked again. I applied it on my RTS and it has never leaked again either.
The product IS NOT an insulating product, however, the brite white color reflects the suns heat. YOu will notice the difference right away in the sun. My RV would get uncomfortably hot, after the application, it would get warm. The RTS roof metal would be hot enough to burn you if you touched it on the underside. After the application on a 90 degree day, the metal would feel cool to touch.
Check this out if you dont mind the white roof color. - cd |

The product is actually 'KOOL SEAL' and is also available from Home Depot, Lowes, etc. it was made to be used to seal mobile home roofs, but what a clever lot we bus nuts are.
Good luck.

Don't overlook Rhinolinings. It's a franchise coating -- polyurethane. Can be color matched too. Makes an indestructible "vinyl" top for your car too. About $4/square foot installed at 1/8-inch thickness. With proper surface prep and priming, it sticks well to aluminum or steel. Also wood and a lot of other materials.
I am seriously considering putting it all over the roof of the bus I'm building. It's most commonly marketed as a spray-on truck bed liner, but it is used on concrete floors in dairies, warehouse floors, and a host of other things. I'm expecting to put it on the floor in the cockpit area as well as on the entry stairs. They spray a splotchy pattern on top of the base coat to provide a non-slip surface. It has even been used to line RV showers. Very tough, very versatile material. |

Hey Clark
You caught my ear when you said used in RV showers. Is this clear, color or paintable??
Can the consumer apply this or does it have to be applied by the contractor?? Where can one find this stuff anyway?? |

There are various franchises out there that provide polyurethane coatings. They are easiest to find in the Yellow Pages under Truck Accessories or something similar; look for truck bed liners -- spray on.
The material is clear by nature, then they add pigments to color to your preference. They can color match to existing equipment, but the accuracy depends on the skill of the worker. My son paints cars for a living and he's one of the best color matchers in all of NE Colorado, so your mileage may vary. I stopped at the Rhinolinings franchise in Fort Collins, CO and saw some of their samples. They can do anything from white and off-white to black and all kinds of colors in between -- reds, blues, greens, etc.
You wouldn't want to call it "paintable" -- it is a high-gloss finish when done; usually 1/8 to 1/4 inch thick, and rarely left smooth. It is tough in a very serious way. The tensile strength of the material is very good (remember they use similar resins for wheel wells in cars). There are other brands/franchises as well, but they all are two-part resin/hardener combinations that set up within 10-20 seconds, so it takes a special gun, external fresh-air supply to the workman, and experience. No place for amateurs or DIYers.
It is also used on concrete -- dairy barn floors, for example -- making it easily cleaned and thoroughly waterproof. With proper surface preparation and primer coating, it adheres very well to steel and aluminum. I wouln't be willing to place any bets on this material over a vinyl latex product such as KoolSeal or ThermalCoat because of the structural inferiority of vinyls and latex in water-based compositions -- particularly in the area of film-to-substrate adhesion properties. That is something that would require some careful testing before you actually use it that way. |

I have this spray-on lining in my pick-up, and have to agree that it seems to be pretty durable. Certainly much better than the drop-in liners. . .
Installer shot it right over the paint - I don't know how much prep work he did prior to shooting the stuff, as the truck was brand new when it was done.
I've got two small chips on the tailgate - both my fault from using the 'gate as a workbench, not due to a problem with the lining. Can get it repaired, just haven't gotten a round tuit.
Must talk to the vendor about different colors, that's an intriguing idea. . .

As usual, I'm confused. I thought Kool Seal was the stuff with silicone beads in it. Am I wrong? Again? I checked the archives, but I still can't figure it out. Do any of you know what is the best primer for this coating? Lord knows I don't want to do this twice. Thanks, all. |

Don,
Kool Seal is not the one with the beads in it. As for a primer, I would read the can as there are a few different brands of the elastomeric type of coating and you can bet they all want different primers if any.
I just coated a mobile home metal roof with Black Jack reflective elastomeric roof coating from Wally World. 5 galls for $68.88, no primer required only the usual surface prep after fixing any holes, etc.

I used the 'Henry' brand elastomeric coating from Home Depot. No primer needed - but it said not for use on new fresh metal. Apparently it likes a little weathering, oxidation and bird droppings to really set-up well. Got the 5 gal bucket and have found many uses around the coach for the leftovers. |

Another idea would be use the roll of "rubber roofing" that RV manufacturers are using now. I think it comes in rolls 8' wide and available in varios lengths. I like the idea of Rhinolinings. Would have never thought of it. Gives me some ideas on roofing and possibly on baggage bay floors. |
