[Greenbuilding] [BULK] OT: repairing cracks in plastic tubs

[Reuben Deumling]

Thanks for all your suggestions. The proximate project involves a small
swimming pool tub. I like the hot glue idea very much, but am open to any
other suggestions or thoughts on specific materials or techniques.
I've also started wondering if the possibility of "welding" is completely
out of the picture. I have a soldering iron...:-) I know some very fancy
plastics are weldable and know this product isn't in that category, but
given the fairly low requirements (aesthetics, pressure, etc.) perhaps this
could work?

Thanks.
