Hi Dan,

I'll be gluing up my first set of tubulars in the coming weeks and hadn't heard about coating/sealing the sidewalls of the tires. Not to ask a dumb question (though I will), but what benefit do you get from this? Does it help with punctures or does it help the sidewalls last longer? Also, I assume you do this before gluing them to allow the sealer to penetrate?

Thanks and congrats on the move! We'll be sorry to see you leave the area, but luckily we'll be able to keep track of you on the forum and through the mag.

Thanks,
Brian

Thanks Dan for the info.

Brian,
The sealant is used to help protect the sidewalls, especially fragile sidewalls like ones found on Dugast tires

it's also used to give some water protection to the cotton-based threads so they won't rot. but on the polyester threads of tires like challenge, it can add a bit of abrasion protection.
