Just read this so maybe a bit late. I was told you only need to season a tarp/tent which has a cotton content. If it is all polyester, which some non-Oz CTs use and most tents use, seasoning will not help. What seasoning does is shrink the cotton around the needle holes along the stitching. Poly doesn't shrink. If poly leaks, or the CTs tub floor leaks, you need to use a seam sealer (available from camping stores). We have Aussie canvas on our CT and seasoned ours once before using it only because we had it up for a few days. If it is not convenient, I wouldn't bother.
