Tentipi Waterproofing

[mark a.]

I'm just back from another 2 weeks in Scotland with my Tentipi Varrie 7 cp. It performed great as usual except that the material has lost its waterproofness in a few places.

I just rang Stunning Tents (who I bought it from) but the official Tentipi impregnating agent (5 litres) costs £91.50 plus £15 postage! Eek!

I know that Tentipi don't recommend anything else (Nikwax etc just coats the surface rather than absorbing in, or something) but has anyone else used either the official stuff or any alternatives? Or could I buy a 1l pot and just fill in the gaps rather than recoating the whole lot?

Cheers.

Fabsil should be cheaper and its designed for canvas. Dont know if its ok for Tentipi tho. Id hate to recommend something that might damage it.

The stuff they use, Acapella ?, sounds odd. They don't sell it in the winter months as it can be damaged by frost.

I think if I ordered it now I'll be ok (no frosts yet in Surrey and the tent will be packed up for the winter once the coating is dry).

If anyone knows if (a) I can just patch it with a smaller bottle of the recommended stuff or (b) use Fabsil etc I would be most grateful.
