Skookum

Having been irritated at how much dirt enters the coil covers on both the Equinox and Manticore, I wonder has anyone discovered a method for temporarily sealing these more intricate designs. Recently, I came across some versions removable caulk, such as these products here: https://www.reddevil.com/products/product/zip-a-way-removable https://www.dap.com/products-projects/product-categories/caulks-sealants/specialty/seal-n-peel/ Has anyone ever tried these for sealing the interior parts of a fenestrated coil?

What kind of tape do you prefer for sealing your cover to your coil? I know there are cloth tapes that can be bought from detector dealers. But, has anyone found good solutions that are easy and quick to buy at local stores? I've tried high-temp duct tape, but the adhesive is rather hard to remove. I'm currently using fiberglass tape, which seems pretty decent, but has yet to run it's full course. I would think electrical tape may be to gummy. What have you used and liked, or not?
