I started using Belgian tape a few years ago. My feeling is that it just creates a stronger bond helping to fill the gaps and imperfections in the tires base tape. I had not given any though to increasing bond life since I check all my tires at the beginning of cross season anyway. If I can move any tire off the rim even a tiny bit by muscling it with my bare hands, I reglue it. So far, all the tires I have with Belgian tape on have two years and do not budge, 8 tires I think. I use Vittoria Mastik, two layers on base tape, two layers on rim, one layer on base tape.1-2-3-4-5 slap it on.
