There's no doubt this product works as advertised. That is not in question here. What is in question is that each tube holds very little of the promotor, and much of it ends up getting retained in the funky brush end, which dries up very quickly. I got 3 tubes with my kit, and I attached lights in 13 different places on the bike. The only way I made the stuff last was to peel off the paper wrapping to see how the thing was made inside. There is a plastic tube, inside of which is a thin glass vial that you break to release the liquid so it can be rubbed on where you want it to go. I ended up not breaking the vial until after I peeled the paper off and then I snipped off the white paintbrush tip. Then I used a q-tip to dip into the tube to get the promotor out and onto the bike. I had to use one tube for every 4+ locations and some locations required a lot of promoter. Had I not been ready to do all 4 places at once, I'm afraid the promotor would have dried up in the brush. You can't afford to do one light location at a time. You need to clean and promote as many as possible, and then the directions say you've got to apply the part within an hour after the promoter dries. You gotta have your ducks in a row and establish a good efficient work flow.
3M Promoter Tube
Single 3M promoter tube. A must-have to ensure maximum tape adhesion. Now offered in a convenient single-use applicator.
We offer promoter in these convenient tubes with applicator tip. Just crush the tube at the dot to moisten the applicator with promoter then “paint” it on your clean mounting surface where you plan to attach the tape. Do not get this product on your hands. Be sure to read the product handling warnings, as it’s a very strong chemical. ALWAYS apply 3M promoter to any surface that the tape will touch. It acts as a primer and ensures maximum adhesion. The key to excellent tape adhesion is to first clean the surface with alcohol then "paint" on the 3M Promoter.
3M Promoter is available in single tubes and 25-pack for dealers and installers.
The process of preparing the surface with 3M Promoter is as follows:
- Clean the surface with alcohol. Be sure to let the alcohol dry completely before proceeding.
- Apply 3M Promoter to the area where you will be mounting your lights (do not get the promoter on your hands - read all product handling warnings)
- Wait 30-90 seconds to allow the 3M Promoter to dry.
- Mount your lights.
Once the 3M tape touches the surface that has been promoted, it will adhear to the surface and is very difficult to move.
I applied the promoter as per instructions. It works great.
