Q. Can I use Scotch Guard on a velour seat cover? Will it make it waterproof?

A. I know no reason not to use Scotch Guard on the velour, and I’ve been told by some that applying several treatments will make the velour virtually waterproof without materially affecting its “breath-ability”. It would seem obvious to me that if applied heavily enough to make it waterproof then it will not allow much air to pass through it either. However, I think the “breath factor” comes as much from the fact that a lot of air is trapped in the nap of the velour between you and the barrier that would result from heavily applied Scotch Guard as from air passing through the material. I can’t personally vouch for that, but it certainly will help keep the velour clean, and make it easier to remove smudges. I’ve never heard of it doing any damage of any kind to the velour.


I have had a RDL saddle on all my steel steeds since 1979. I will always ride an RDL and is the only saddle I recommend for long distance riding.
