3M 4298UV Adhesion Promoter - Tape Primer 4 fl oz / 118 ml Bottle with 0.750" x 0.312" Felt Tip Applicator

Was buying these in a packets, this is so much easier and less expensive. It dries clear in color and being a 3M product it is a great quality product. The bottle is a good size to store in a small cabinet. It functions great when trying to get dried out double sided tape to re stick to something.

This stuff is absolutely necessary for tape on trim. Works awesome with the 3M tapes. I'm sure its quite toxic so wear gloves and use in ventilated area.

A must when you are using double sided tape. Just appy to any surface you are working with and it makes stick to the tape better. I used on automotive emblems and it worked great.

A must whenever you use automotive tape on an automobile. I'm talking about two-sided 3M tape. Adding this stuff and following the directions makes the tape work like bolts would. Excellent product!

If you are using 3M tape, this is a must. Makes all of the difference in the world for a good strong connection.

Good but used need to have a lot of usage for it

Good stuff! If you need it, then you know! Very functional, dries fast and is relatively easy to use. Much better value than buying individual pack but will dry out if you dont replace the seal under the cap due to the felt tip.

Whoa, this works. The comments online about this were mostly about vinyl wrap, but I needed it for decals and Eva Foam on a polyethylene boat (Hobie Cat, same material as a kayak). I did a test run before and after to see how it did. I'd say on a scale of 1-10, 1 being like packing tape adhesion , and 10 being permanent, The "without" stuck at about a level 4, the with, is an 8. I can still peel the EVA foam off, but it's not easy. Fantastic!
