rubber roof sealant/paint

[Pizzarco43]

Actually, we painted the entire bus portion of my truck with the Lanco product 2 or 3 years ago (rolled it on) and it continues to look good. I suppose there could be some negative effect on air flow but I have decided not to lose any sleep pondering that question.

Is it a similar product to Henry's?

I used Henry’s seam sealer two inches on either side of every seam and around every rivet. The applied a coat of Henry’s Tropicool. Absolutely cleared up any leaking issues I had.

I have heard of "Henrys" but don't really have any experience with it. Maybe someone else can answer that question.

Plus it will add some strength.. yeah it may cost some change, but to me it would be worth every penny

Add strength to the bus?

Resale value.

I have found it easy to apply, attractive, and cost effective.

Do you use the area between the cab and bed like a sleeper cab?

Yes, there is a matress and bunk over the cab and I can sleep there when I'm hauling horses long distances. I did not do the conversion but when I got it there was the jackknife couch from the original motor home in the bus part. I removed that to give more room for equipment.

I patched my roof exits a month or so ago. I did what I thought was a nice, tight job. WRONG! We got a couple days of heavy rain for the first time since they were installed. They both leak, one was bad...the other not so much. Fortunately I was watching & had buckets to catch the water before it ruined my nice new floor! I was able to figure the problem by blowing air up into the rivets...several of them were blowing bubbles topside. I drilled them all out & used 1/4" sheet metal screws (up from 3/16" rivets) to fill all the holes this time. I covered each hole & screw threads in sealant first, tightened them up & goobered around the heads with sealant as well. I'll let things cure overnight and simulate a downpour tomorrow to see how the second try holds up. I think I'll be good to go.

Anyway, as long as there are NO leaks... as insurance, my plan is to tape off each patch to about an inch our two either side of the rivets/seams & coat with Flex Seal or some other elastomeric like coating. I'm not going to paint the whole roof with the stuff. I'm looking for something with the consistency about halfway between the sealant that comes out of a caulking gun & just regular paint. I've got marine maintenance enamel for the roof, but want it sealed up good before I take that step.

What product have you all had luck with?

I think I'm going to buy a gallon of the white Flex Seal unless someone calls that out as a poor decision. Again, I'm only planning on using this as insurance, only applying once I know I'm leak free without it.

any luck with the flex seal? I've got a fiberglass shuttle with a patched roof and am looking to cover it all in a single membrane.

Interesting thread, thanks to everyone who has posted.

[Pizzarco43]

I don't have any experience with Flex Seal. It sounds like you have identified your problem and effectively addressed it.

[Jessiekij]

I doubt that would work on a curve-top fiberglass shuttle bus? There's a solar panel mount and roof vents as well. I was thinking more of a paintable product.

are you addressing the rubber sheet roofing? - I'll see if I have the video handy that addresses vents

I did have some luck with it. I used the flex seal in combination with a roof sealant caulk recommended by a local camper manufacturer. First the roof sealant on the seams, then after a couple days of cure I rolled the flex seal from a paint can. I also used the aerosol cans of flex seal on all my rivets...both new and old. I only sprayed it on the interior and exterior rivets before I covered them with the rain gutter. No leaks!
You can see how I applied the flex seal on the roof. Going to paint over it with marine maintenance grade white at some point.
