plastic weld on - where to buy calgary

[calkrog]

i need some plastic weld-on for plexiglass. been to canuck tire and homo depot but nuttin.

i built a platform for my skimmer last year using plexiglass but the silicone just gave out when i removed it to clean below it. looking to make this thing last a bit longer this time, plus i dont like having to wait two days for the silicone to dry properly.
