Not sure what kind of plastic fittings he was referring to when stating that Great White isn’t plastic safe but for the most common plastics found in aquarium fittings and plumbing, it’s perfectly safe. I’ve used it for years and never had an issue. In fact, I have fittings on my tank that’s were sealed over 10 years with the Great White and never had a leak. The key to using this stuff properly is to not evertighten the fittings. Here is the info right off the label and it discusses the materials it’s designed to work with. I have the utmost respect for Russ but my expereince with the Great White is different but again, overtightening could be a factor if you aren’t careful.
