At risk of stoking the ire of some, I'd like to add a bit about my use of seam sealer in rehabbing old tubulars. I had a set of Clement Futurox tires that were in very nice condition other than the latex in the sidewalls was dry / flaking.....hope this makes sense. I used a soft wire brush to gently clean the loose latex from the sidewall cloth and applied two coast of tent seam sealer to the sidewalls only with an acid brush. I used Barge cement to reattach the rim tape in a few spots where it was loose, then mounted the tires to the rim with Vittoria Mastik. Two years later, the tires look great, the sidewalls remain pliable, and I ride them without concern.

I appreciate that some will not ride or repair old tubulars for a variety of reasons. I have several that I would not invest my time to fix or my skin to ride....'not sure why I'm saving them.
