3M Primer 94 Pen 0.2oz | Vinyl Car Wrap Application Tool (5 Pack)

I used these to prep a chrome metal surface where I was applying a domed vinyl decal. I could tell it did enhance the bonding of the adhesive on the back of the decal. I'm very satisfied with the results. The reason I used this prep pen was because the surface I was applying the decal to was slightly curved and I wasn't sure the decal would stay bonded to something other than a flat surface. Worked well. I allowed about 5 minutes after using this product to allow it to dry before applying the decal.6/19 update. The product continues to perform well.

I like how when used properly it keep whatever you are bonding together stick

Ad shows 10, but you only get 5. Works great though. Would not use VHB without this primer.

Excellent and works well. Ordered b/c the reviews, on moonroof air deflector i ordered, complained it didn't stick well. I ordered this and 3-M double sided tape. When deflector arrived i removed the inferior tape used this pen on both the auto and vent and applied tape and placed vent on car. Stuck very well and solid.I believe this is a must have in preparation for applying anything you really want to stick well. Also best price at present.

We use Primer 94 at work all of the time for vehicle wraps. Generally we will get the can, but it's convenient to have the small pens handy to keep in our bags for doing on site installs. They work great without having to carry around a can and brush. If you go through a lot of primer, you're probably better off getting the larger can for general use, but having a few of the pens on hand is invaluable.If you've found this review helpful, please let me know by clicking the button below.

Love these little sticks for wrapping car interior parts with the 3M carbon fiber DiNoc. Makes sure the wrap won't lift on the harder to work with spots

When I opened first one, it's not working. And I just keep breaking something inside but not working at all. So I google it then I found it why. That one is already got some damage or something so it's been already dried out. So I try second one then I can see some liquid inside then I pushed and cracked it and working very well. But I got 2 damage one out of 5.

So far this has worked fairly well. The two materials did come loose once, but it was under very hot conditions. My real complaint was the complete lack of any kind of instructions. I wasted one pen just attempting to open it to access the glue. If you are going to sell on Amazon, I feel,it would be safe to assume that not every purchaser is an expert.
