Momentum silicone for external over flow??

fishbox · Feb 28, 2017

Is this the right stuff?? Seems expensive... I'm using it to build an external over flow and also to add eurobracing.

I don't know if it says RTV I think you want something more like

That is the correct silicone to use, but only if you're doing glass to glass.

RTV 108 is the right stuff to use on glass but it will not work on acrylic. I would also shop around as $28.00 a tube is a ridiculously high price. Here is where I have been getting my RTV 108 from https://www.zoro.com/momentive-rtv-silicone-sealant-101-oz-cartridge-rtv108-12c/i/G2066102/

Yes it's glass to glass. And and now I'm mad because I already received it and it shipped from the company Alex posted the link for which is 1/3rd of the cost

I'm calling them

I am guessing the Amazon seller Home Comforts Inc might have bought it from Zoro and had them ship it directly to you. I hope you can do a return and get it for the lower cost.

Yup, that's exactly what happened. I opened a ticket for a return and it said they'd email me a return label but I haven't received it yet. To be continued.......
