3MPrimer 94 Pen 3-Pack | Car Wrapping Application Tool

Other reviewers have said the ampules are small and don't contain much. That's rather true. I pulled four small trim pieces from my car to wrap, and needed all three pens to cover their perimeters, since the vinyl was being heat-stretched around all the edges. Worked out well for me, but if you're working on any kind of larger project, get the can and a paintbrush. Time will tell if this stuff worked out, I'll update this if my vinyl ever releases.Also, take note: crack the ampule once to release the stuff. You won't get any more primer out by breaking them further, but you just might get an incredibly sharp metal shard to poke out the side and slice your finger open and fill the wound with toxic goo that burns like you wouldn't believe.

This is my second 3 pack that I expect to use at a later date to replace one of my deflectors that did not get installed correctly. I used the first 3-pack to install 3M tape to Window Air Deflectors and then applied to the vehicle per instructions. The holding strength appears to be excellent had I not made a mistake (see below).I have 1 warning. Before applying the primer 94 and removing any tape for mounting, practice putting the "piece" in place where it will go. You only get ONE chance. Once the 3M tape hits the primer 94, it is there to stay and you will not be able adjust the position. I was off just a little and applied a slight downward pressure to get one end of the deflector into the right place. That end had too much stress pulling on it and it did hold as I had hoped, but the rest of it appears to be very solid. I will replace it at a future point in time.The second deflector I practiced putting it into place and used automotive masking tape on the vehicle to mark the exact position of each end of the deflector. Then I practice putting it into position multiple times to make sure there was no twisting or pressure being applied during the installation. Once comfortable, I applied the primer, removed the tape cover, aligned the two ends at the masking tape marks and it installed perfectly with no twisting or stress being applied to the joint. The deflector does not even vibrate in the wind at 70 MPH on the interstates.It's true. Practice does make perfect. Also be sure that the surface for the adhesive is clean. I used alcohol.

Useful for creating a more permanent adhesion for vinyl wrapping projects. Especially along edges. Good stuff. The pens do dry out pretty quick, so make sure you have the surface prepped and you know where you want to brush it on before cracking the tube. If you have a large area you want to cover, you may be better off buying the canned version and brushing it on. But the pens are inexpensive and good for small projects.

easy application and clear instructions. what else do you want, its tape primer. better than skipping the priming step

I needed this because I bought the most beautiful peacock colored vinyl wrap with the intention of wrapping my husbands PS4 controller as a surprised. The vinyl itself, while beautiful, was subpar in adhesive quality even using a professional grade heat gun. So, I bought this for support. It did the job and I was able to get the vinyl to adhere to the controller. My only issues with this is the quantity. Once you pop one open, you have to use it IMMEDIATELY or it dries out pretty quickly. There is also very littler quantity. I used all 3 tubes for one controller. It also has a very strong odor, so be sure to use in a well ventilated area. Gets the job done but I feel like there could have been something better and easier to work with out there.
