OK found out that my tank is made of polyethylene and you can't patch with fiberglass. So I started looking for information on the internet U- Tube had great info on the how to repair it you must use polyethylene rod and soldering iron it looked like a 40 watt. They don't tell you where to get the rod you need. and if you over heated you will make the hole bigger. They sell plastic welding machines they are between 1000.00 & 2000.00 Yea right! OK I will find the rod and we will try this ourselves. ( Which means I will supervise with my hands on my waist and my husband will do it, while I give him instructions he doesn't need until he gets frustrated and says STOP! ) In my search I found company that not only sells the rod in small amounts because other companies sell them in a large bundle ( too much money for something I will probably not have use for later) they sell a kit that comes with everything for $47.67 The company is called Tool Desk @ www.tooldesk.net ; and it includes an instruction manual, 15ft/ of natural polyethylene rod and a special 40watt soldering iron that you insert the rod though and melts it at the correct heat temperature its call the "ATV Fender Plastic Welding Welder Kit Urethane Supply" (long name) I will order one and let you guys how it works. It will have to be next month very short of money. We moved into a smaller house now that we retired to down size and are selling the house we use to live. We just put it on the market YEA!!! it took my husband and I ( and I did work; I completely painted the whole house inside by myself, and that house has so much wood work) 6 months to remodel; so we are tapped out. Everything wasput on the back burner, but I will be sure to let you know how it works.
