52 hubcap problem

[artron9]

Hi! My 52 Vic has original hubcaps. On occasion, one has fallen off. I've carefully bent the prongs close to the original position but I think the metal is getting tired. I want to keep the original caps and do not want to pay for new ones which will probably be in the same condition as mine. I was thinking of putting a clear silicone bead around the perimeter and pressing them back on. Any other ideas? Thanks for your input. Ron
