I just bought some 24 inch to 27 inch universal screen protectors clear glossy from my local computer store. The universal screen protector costs me $7 each The concept is the same as the Guitar Condom, but no way I am paying $20 for just a back finish guard for my Fender Jazz bass. Going to use an exacto knife to cut out light outline of my bass back shape and the Pickguard shape. Then I will cut it with scissors and peel off the adhesive side and get it on my bass. I don't think the adhesive of the screen protectors will do any damage to the bass finish since it is silicon static based.
