Helps fill in the gaps, at the Top.
I used the Frost King 3/8 in. x 20 ft. Grey Poly Foam Caulk Saver for something totally different from it's original purpose. I recently remodeled our bathroom. In it was a Hot Tub-Spa, which also was rebuilt throughout with a new epoxy paint job. There used to be a gap on the mirror wall sides. So, with the Frost King Rubber Seal + 3/8" Grey Poly Foam Caulk Saver (foam piping), I eliminated the gap. I'll add pics to so show the improvements and other uses for existing products. This worked out Beautifully. Wrapping the Frost King Rubber Garage Door Seal around the Frost King 3/8" Grey Poly Foam Caulk (size depends on Gap fill size) Foam Seal makes a nice water tight seal. Installation, I used the wooden paint stirrer (looks like a tongue depressor) to push both sides of the Rubber Seal down . I hope these Pic's demonstrate enough detail to visualize the seal on the mirror wall sides of the Hot Tub. Helping others, Safety First.

    A very good filler for whatever project you have and think of. I have filled the space in between the counter top and my range oven so that nothing will fall into the slot. It is also good for sealing the space when the window does not close tight and leaks air.

    Frost King Grey Poly Foam Caulk Saver was exactly what I needed! The product's 3/8" radius filled the gap between the bath tub and the shower enclosure. The product was long enough to two of the gap filling around the bath tub.

        I have a 2013 Nissan Frontier that had rattling doors,...
        I have a 2013 Nissan Frontier that had rattling doors, all four of them, because the rubber seals have gone South and, even though they still seal, they do not provide good isolation for the doors and the doors continually rattled against the sills and it was quite annoying. So I researched it on the internet and found that a guy had the same problem with his old Chevy Tahoe and he tried the same thing. To insert the 3/8 " foam caulk saver into the empty core of the door seal gaskets suing stiff string trimmer plastic line, duct tape and Super Lube grease to make the tube slick enough to slide through the seal core. It worked like a charm and my truck is as quiet as it was when new. I never would have thought of using this Frost King 3/8" Grey Poly Foam Caulk Saver this way. But it definitely works quite well.
