I've been reading some of the posts where a few members have tried Zinsser Watertite Mould & Mildew-Proof Waterproofing Paint as a filler. I'm just about to canvas a 14' Huron and was thinking of giving it a try. My problem is that I am having a bit of a time finding it in my local paint/hardware stores. They will order it in but that will take 3-5 weeks, which kind of defeats the purpose for trying it in the first place. I'm looking for something fast, cheap and good (as mentioned in some of the posts). If I have to wait that long just to get it, I might just as well use the regular filler. The canoe will be in the water sooner. However, I did come across two other brands that seem very simular and I'm wondering if anyone has tried either or if any of the chemists out there can tell if it's close by looking at the ingredients list?

Maybe it's just the wording.
