I don’t do this for a living at all... I do imagine heating/cooling/heating again plays on material... he’s made 2000 tanks for 20 years... I’ll take his word over... well... anyone with less than 20 years n 2000 tanks experience...I can understand the crazing part but Think about what you're saying that if you cut acrylic in a certain way it will get stronger. If you believe that I've got a bridge and some magic beans to sell you. The worse it's gonna do is just sag over time Won't hurt the tank
Just saying...
How much are the beans?
On another note...
