OK Everyone, Maybe I am missing something here but I am having no fun rinsing these tanks with acetone. The instructions say to tape of the holes with strapping tape. Every time I go for a rinse, the strapping tape falls off as soon as the acetone hits it. I have tried a lot of taping options. No go. I am about to install all the fittings and add a short piece of hose to pinch off but I was hoping I wouldnt have to because I want to avoid those fibre glass threads as much as possible. Any tips?
