Screwed up silicone job. Need DIY help

[FishyFishy!]

I've re-sealed many tanks without taking the panels apart. I just razorbladed all of the old silicone on the joints, used rubbing alcohol to clean it well, masked and siliconed. Worked great every time for me. I think the seal inbetween the panels should be fine, no need to take it all apart if you don't want to.
