I'm sure you'll find plenty who don't venture on here who used some normal clear bathroom silicone without a problem and others who have had an issue. You'll find a few less with sikkaflex who've had an issue but there are still some who will. Tec 7 looks as though its close in concept to sikka... so suspect you'll be fine. If it fails you'll not know for sure if sikka would have too...
