I use the Plaid Blue and Black label acrylic sealer on mine. I still have some paint rubbing when putting the helmet if its tight fit. I have found that I actually have to sand the insde of the helmet to make it a little bit bigger so it is no so tight. If your looking for the Plaid Sealer, you can usually get it from Walmart or Michaels and it comes in Matte and Gloss. I usually keep a can of both around depending on what I use it for. Below is a pic of what the can actually looks like. Hope this helps you out.
