I want to paint my tank and started to remove parts off it. No problems with knee pads (I was surprised they are still here- it was so easy), then broke head of one bolt keeping tank badge (that's my problem), then removed both bolts on other side to see construction. After both bolts are removed I can't remove badge and rubber under it! No bolts needed But what is the trick? Is it glued (better than knee pads) or rubber stick to metal so good in 10 years?
