I go through ProTuff Decals. They have our information on file so re-orders are simple, and they allow me to send custom designs that they turn into decals. Yeah, every team has to apply their decals. Helmets go to their parent company (we only deal with Riddell), for reconditioning and recertification after every season. They come back freshly painted and with a certification for the current season. Helmets are only allowed to be recertified for 10 years, after which they are no longer eligible to be used. The decals are easy to apply and are actually easy to remove within the first couple days if you want to adjust the location. The adhesive really doesn't "lock on" to the helmet until about after a week. At that point, removing the decal is much more difficult, and there is no way it can be reused. Taking it off doesn't require a heat gun, just a good strong pull. Sometimes, if there are several layers of paint from older helmets, taking off the decal will remove the paint down to the original shell. It's why the head coach no longer lets me use stripes down the center. I pretty much learned through trial and error. A lot of the kids were putting the logos at all sorts of wrong angles and it looked horrible to me so I took over doing everyone's helmet. Roughly three to four per day during the summer practices.
