RTV 108 suppliers

[Dyspnea]

I've bought a new to me 265 gallon aqaurium, it has been sitting empty for over a year, the seals look good but are a little rough. To be on the safe side I want redo the seals.

The best consensus is to use Rtv108, but having a hard time finding it. I went to Ackland grainger but they don't carry it or couldn't find it. I know grainger (USA) carries it but the clerk said thats the US. Anyone have a parts number or sku for Canada?

Ive tried ordering online, but the places I have found won't ship to Canada, of course. Any canadain sources? I would like to order it and have it by next week.
