im building a rubbermaid bio filter would ge II window n door be fine?will it stick to the rubbermaid tubs or if u guys have any other suggestions id appreciate thanks
Silicone does not adhere to plastics well... there are other adhesives that will better wuit your tub...
But what are you gluing in place with it?
If it is plastic to plstic... or plastic to plexiglas... the PVC cement or a similar type product will work best. As opposed to "gluing" two things together these types of products "melt" the plastics then allow them to "dry' as one piece... often explained as "welding"...
I also agree with the above advice regarding silicone
