Loose Lens Hood

The lens hood on my Pentax 16-45mm began to work loose ... so, with trepidation, I did the following.

(Only copy this action AT YOUR OWN RISK!)

I removed the hood and placed small a blob of super glue on each of the 3 lugs on the lens hood, and LEFT IT OVERNIGHT to dry.

The next day I put the hood on the lens and then quickly removed it again, just in case it stuck.

I waited another day ... and now the hood is a tighter fit and all is well.

Is there an easier, and safer way, to increase the friction and keep the hood firmly in place?
