I have used various forms of silicon sealants for years and it seems they all have the same problem. They seem to be made for single uses. By that I mean they harden in the tube. I'm sure the manufactures love this. I'm not talking about cartridges but tubes for small uses. Is there a specific product that I can use , recap and use again and again in small amounts? Any help would be appreciated. Howie K2MME ________________________________________________________________________ Try Juno Platinum for Free! Then, only $9.95/month!
