Well I got mine mounted and I think they are going to be great.
On a dry trial fit I found the right side fit very well and the left did not follow the tank as well. Daryl had noted this may be the case in a post above. There are butt loads of posts about Safari tanks not fitting well or deforming when removed,ect, ect....so I'm sure no two are the same. Once the adhesive was applied it fit fine. This is how I did it.
I resisted the urge to spread it out and just left it in globs. My father in law is a wood working hobbiest and has every kind of clamp known to man so I borrowed an assortment before starting and guess what? None of them would work. After some head scratching and a beer or two this is what I came up with.
Cam straps from my white water gear bag. These worked great for holding them in place without flexing them.
The painters tape was probably not needed but it made me feel better. I'll post up a finished pic when after I get it all back together.
