Gap Sealer
A wonderful product that fills those difficult gaps. Easy to use and stays flexible. D

I had high hopes but product doesnt dry hard enough
Product appeared old and was sticky on my hand skin. Finally, after shaping product and leaving it several days to dry, I found product to have hardened, but not hard enough. I could reshape product and it wasnโt a good seal-used around the sides of ducted diffuser. Back to the drawing board. Or, next time you cut your floorboards to install a diffuser for the ducting heating, make sure you know how to use a hacksaw. Try to cut diffuser housing spot-on or youโll be forced to search for sealants that perform lower tham expected.

The adults version of playdough for your DIY
I love this stuff, where has it been all my life? I had an electrician tell me about duct seal and it changed my life (I mean in terms of if I need to cover holes for any cables/wires/pipes that come into or out of my home). This stuff is playdough for sealing holes and making sure no critters get into holes that might remain from wiring, piping or conduit. If you're someone that DIYs around the house, get this for the odd hole you might need to just plug and forget. Great value, it stays malleable for a long time, retains the color and great ease of use.

Perfectly flexible but sticky to nitrile gloves.
Product arrived quickly, nice and pilable which is perfect for sealing ducts. A little sticky on nitrile glove. Recommend invitation into the vine program.
