PROtastic Industrial Strength ORIGINAL Tac Tack Black Putty (1 metre long x 2cm wide) for Repairing, Reconstructing & Protecting Objects, Mouldable Repair Putty, Removable Waterproof Glue Putty

First time I have used this stuff but I am very impressed by it’s performance.

Using to hold things in place and even took the risk of using this on its own to hold a couple of test motors with propellers in place on a board. They didn't budge a mm and I still have limbs. Excellent stuff!

We bought this to tack a cable from a USB socket, to a HUD (head up display) in our new car. It certainly is fairly sticky and holds the cable, which is now tacked out of sight. It didn't really leave a hideous residue of hands, as some others have suggested.

Excellent product, clean, easy to use and it works!

Does what says on the tin, and does it very well

We have a lovely cast iron fireplace, and the removable curved front grate was letting in a lot of cold air, or drawing warm air out of the room via mounting holes. We didn’t want permanently seal it with silicone and damage it, so this black putty is the ideal solution.It’s a great product, mouldable and flexible and has sealed the mounting holes exactly as we needed. Drafts are gone. 😀Looking at the grate from a distance you would never know the putty was there.The fireplace is not working, but if we ever decided to sell it then the putty can be removed.Really pleased it turned out so well. Wish I had found it sooner, as it has been an annoying draft since I moved into this house.Super swift delivery.

This product claims to be weatherproof, but it definitely isn’t. We had a light sprinkle and it lost all tackiness.

The material is quite amazing, holds fast to that which it should but can be pulled of if needs be and start again with no mess.
