I started foaming my 54? corner unit today- sorry no camera...
I had a really old bottle of GS that expired in 2003.... new unopened bottle. It wouldnt spray, so I put on the safety glasses, put it in a cardboard box, took a nail and a hammer to the bottom edge of the can.....
It worked great- really fast!!!!!! but great.....
Anyway.... I got a thick layer of foam in on one side- No choice- couldnt stop the spray.....
I let it sit for about 30 minutes and checked on it. It skinned over real nice but the thick sections were still soft under the skin...
If you press a part of the foam... it plumps up in other areas...
You can pull it a little here... squish a little there..... You can change the size a decent amount after it skinned but is still squishy inside.....
I put the tank on another side so the foam was vertical- taped on a weight here to pull this out... used a piece of pvc tubing to squish this in- etc.... I left it that way for another 30 ish minutes, and the changes I made are now permanent since the soft foam inside cured to the dimensions I wanted. ( I also stabbed the thick sections with a wire clothes hanger to get them to cure faster as well)
Neat little trick I never read about anywhere, so I figured I'd pass it along.
BTW- I used GS and touch n foam black pond foam- The touch n foam is definetly a denser foam- also cures faster and more ridgid. GS is softer but "airier" if thats a word....
So far I'm quite pleased with how the tank is turning out- wish my camera was working to show you the changes in the foam.. I think I pulled out up to 1.5" and squished about 1" which can be a significant change.....
