Suction Cup on Fiberglass

[CapnMorgan]

Is it bad to put suction cups on the fiberglass walls of the coach? Is there any realistic possibility that it could delaminate the fiberglass from the plywood underneath? This is a small one, but I have another that is a little larger that I was thinking of using for attaching my home made 'genturi' for the aqua hot.

I put several of the Command brand hooks in the bedroom to hang jackets on. After a couple weeks I could tell the vinyl covering over the plywood walls was pulling away from the plywood. I took them down right away. Probably not a good idea with suction hooks either.

I wouldn't think those suction cups would cause delamination. Some of the exterior windshield & window sunshades use suction cups to hold them in place.

Will not hurt the fiberglass, But I have seen marks on painted surfaces.

During Quartzite Week this year, one of our esteemed members purchased 2 for stabilization of a second solar panel. There are now 2 three inch "circles" that won't polish or compound away! Located dead center in front generator area.

As I would expect and has been mentioned, they would probably leave a mark on the finish. I would think they could be removed though with some rubbing compound.

if a suction cup de-laminates your Fiberglas, you have other issues that need attention.

Ha, good one, that's what I thought, but I have learned the hard way that it is simpler to ask dumb questions, than to feel dumb for not asking simple questions.

I use those cups on my Clear Coated gel coat. Of course the clear coat is 17 years old, but I then had to repair the clear coat at that spot.

I can mount the suction cups on window glass to stabilize the genturi. I just have to remember to do that!!

CapnMorgan....Since you made the Genturi, how about making a support bracket. I made one for mine that drops into a slot between bay doors.

Don, that is a very nice job and idea, unfortunately I don't have as much room as you did, but more importantly I'm not sure my meager collection of so called skills, would get me such a nice work product.

I think I can manage with the generator exhaust by using suctions on the window. I don't have windows above the exhaust stack for the HydroHot, so I may attach some small metal brackets to hold that one (its out of the way behind the slide). I assume the coach has plywood backing up the fiberglass, does anyone know what size screw would be safe to use? I don't think there is any wiring in the walls, but I would hate to find out the hard way.

My rig has canvas snaps for the windshield screens installed. However, there is airspace (but no plywood) behind the fiberglass at those locations.

If your rear furnace is inside the coach not the basement, remove the exhaust grille on the outside and check the construction of the side walls.

I and the manufacturer have used 1/2 inch screws on the inside side walls and created no new holes in the fiberglass exterior.

Maybe the snaps would also be useful for the tie down you need? The pipe does not get hot and is very light so even with a strong wind might be secure.

Hey Don for my Gen Turi I use a large suction cup on the window, I got mine from Home Depot in the ceramic tile section. It is used to lift up old tiles. It works great. I like your idea also.
