Hello, I'm researching an acrylic build in the 8'x4'x34" range out of 1" material. It seems like most guys that build their own tanks use Weld-On 4 but I spoke with one commerical builder that says he uses Weld-On 40. I've practiced with the 4 and it seems pretty darn easy to work with. The 40 seems like it would be a pain and you have to mix it. Does anyone have any insight/experience with either of these options? Thanks.
