Sealing Girard window awnings and slide toppers to coach


Recommended Posts

On our 2005 Signature the rubber seal that Monaco used between the slide topper housings and the window awnings and the body was allowing water behind the housing and onto the top the of the slide. Sometimes the water would make its way into the floor.

Monaco used an inappropriate rubber seal and not the one recommended by Girard.  The seal Monaco used was the same as the seal that runs around the top of the windshield to channel water away. There is no good way to create a watertight seal with the body or the top of the slide topper, especially after it hardens and shrinks a little with age.

I replaced ours with this:

Trim-Lok P-Shaped Rubber Seal – EPDM Foam Rubber Seal with HT (General Acrylic) Pressure Sensitive Adhesive – Door & Window Weather Seal for Homes, Cars, & Boats – .5” Height, 1.25” Width, 100’ Length

It lays with the flat part horizontal and the round part against the body.

I added 3/8” VHB to the top of the P to stick to the body.

3M - 4611 0.375" x 36yd VHB Tape 4611, 0.375 in width x 36 yd length, 1 roll

I also used the following adhesion promoters.

For the VHB to the rubber

Finally sealed the edges with this:

I use masking tape to get a clean line on the clear sealant.

Finished installation. I fixed this back in GA’s Dixie Dust season when pollen covers everything.
