Hi Jack,
thanks for the speedy response.
The rib is absolutely solid, no separation and doesn't move at all. It does though look like there is a very tiny section of solder starved joint approx 1/4" long on one side. It is through this tiny gap where the moisture comes from. The daft thing is I never ever use this gun in the rain and it is absolutely bone dry.
Would it be possible that solder residues could be gathering moisture and seeping out through this solder starved spot, or is it just flux. Its tiny spots of clear to brownish liquid and they appear there after the gun has been wiped down and stored.
many thanks
Jonty
