Hello,
I have a few questions about making some rock ledges for my leos. I have already siliconed 2 plexi glass shelves into my 50 gallon breeder tank. I was planning on putting tile grout over them, but the people at the hardware store said it wouldn't stick. I got some acrylic latex window glazing made by elmer's. I was wondering if it is safe to use this? I was planning on painting over top of it then putting a coat or two of polyurethene over the paint, to seal it off? Is this ok to do??
Thanks,
A.J>
