you dont really need to do the smoothing part though. If you lay the bead smooth and even over the seam it will cure and seal just fine. Smooth out any pieces that pull away when you pull the tape, but you really want to touch the silicon as minimally as possible. If you lay the bead, smooth out, then pull the tape, you are more likely to cause a problem then you are to fix it imo. Just lay as even a bead along the seam as possible and then pull the tape. Dont touch unless you absolutely have to
Okay, tank is all sealed. That wasnt much fun. The RTV 108 stuff is good, but its more of a sticky silicone....Very hard to smooth out after you get it in the crack. Even wetting my finger down didnt help much. Caused a couple rough surface spots, but the seal job turned out good. When they say you have 10 minutes until it skins, they mean it. The last piece of tape I pulled had skinned in one small spot. Will need to trim that up with a razor knife in a few days. Im attaching some pictures of the silicone job, and the tank and stand refinish progress.
One thing I found out, is that the rtv 108 stuff will not have a really smooth look like the factory.....close but not quite. I used a credit card with a corner cut off to do the bottom seams. It worked well. For my 135 gallon tank, I used 1.5 tubes of the rtv. In a perfect world, youd have one guy laying down a bead, one guy smoothing it out, and one guy pulling tape. Two people are a must on a big tank.
