White Waterproof Duct Seal Putty (3 pcs), Moldable Plumbers Putty and Sealing Clay for Indoor & Outdoor Use – Quick Mending for Air Conditioning Holes, Drain Connections, Ideal for Wall Hole Repairs

Works great for covering/sealing electrical piping and wiring holes in your exterior siding. White color matches white siding. A little more expensive being color matched but worth it.

Don’t waste your money or your time, it says it’s waterproof but waterproof my ***.

This product works as described. It is easy to apply and it is worth the cost.

Worked great, I used it to cover up some rust around the overflow in my bathroom sink, it dried in a few days and then I trimmed it to look good

Took forever to harden

Not that good at all didn’t hold won’t buy again

Update: Changing my review to 5 stars due to the quick response and help from Qidarusxl to resolve this.Waterproof Duct Seal Putty (3 pcs), only received 2. Looks like the the packing was opened and one is missing. A return the someone used 1 and returned the rest ???

There are a whole number of ways to use this stuff, but it particularly shines as a plumber's putty. It is stretchy and pliable, and can be molded stably into different shapes, as it sticks to itself. Creates a nice seal where needed. They've also included a full THREE individually packaged units, which is more than enough for a number of different jobs. It sets hard so that you can shape a contour when ready. Everything I need to fix a damaged rail...
