Ive done two so far, and they arent that bad. Takes a really long time and a lot of scraping to get the old silicone out. And, you have about 5-7 minutes to get the tape pulled when you silicone the seams. It sets up way fast. And when it does, it leaves a hard edge where the tape pulls, and there is no way to smooth it out (rtv 108) Did that on both tanks on the last pieces of tape. Ideally have someone putting the silicone down, and one person immediately smoothing it out, and another person pulling tape right away.
Next tank, Im buying new, haha!
