How to patch a leak our water tank?

My starboard tank cracked several years and I went online and purchased a plastic welding kit that is used in the auto collision repair shops. It came with a video and several different plastic welding rods. It worked great and I still have enough rods to do about 40 more cracked tanks. Hopefully that will not happen, but if anyone wants to borrow my repair kit and your in the Philly area just post a PM.
BTW the weld has held up for about six years of fairly heavy travel

Darn- should have talked to you a few hours ago! I'm right next to Philly.

I used TAP Poly-weld. It's about $13.00, and if you follow the directions (which includes a heat treatment to the part) it worked well for me where a fitting was not properly bonded to the tank. I cut a "washer" (=patch) from a milk jug and glued it over the area to reinforce the repair.

TAP Plastics has a YouTube video that shows the process. Here is the link to TAP:
