Re: [Killietalk] Acrylic bonding

["Karen Perdue" <windamyr at peoplepc_com>]

Hi Lee,
can you share where I might find this weld? I have looked all over for it
here, and eitehr I'm asking for the wrong product, or I'll have to go to the
"big city" to find it. Any product names would be helpful, and GREATLY
appreciated!

I'd like to build a HOT refugium for a SW tank, but the silicon sealant just
doesn't cut the mustard<G>

TIA!

Karen
