[snip] Roy Lewallen, W7EL HI Roy, I have been using a different product for over a decade that works great - liquid vinyl tape. It does a heck of a job for sealing water-tight connections and, like RTV, doesn'g get hard and crack. You can buy it a most hardware stores. Its easy to use and, like was suggest earlier in this thread, I first wrap the connection with regular vinyl tape (a single layer) before appling the liquid compond - its makes for much easier removal when needed. I've pretty much switched completely to the Plasti-Dip stuff myself. It is readily available in at least two colors--red and black--at Lowe's. I used RTV, both the acetic acid and non-acetic acid varieties through the years. After a couple of unpleasant corrosion experiences with the acetic acid type, I began either wrapping connectors with vinyl electrical tape or spraying with acrylic sealant and then applied the RTV. Either way works well. I recall seeing cautions that one should be wary of black RTV in that it could conduct. I don't know whether it can break down but I've used the clear product. Dave Heil K8MN |
