supercast pm help

Hi all, I have a supercast pm and recently have noticed that the top half is very loose where in connects to the bottom half almost to the point of coming apart when casting. Just wondering if anyone has any advice on how to tighten up the connection, thanks.

rub a candle on the spigot the wax will make it tight

put some candle wax on the male part.

Thanks lads I'll give that a go
