Lapping compound is the white crap which forms on the jowls of large dogs that you don't want to touch.
True story...this winter I was in the AutoZone in Fall Rive. The kid behind the counter commented on how he liked my jacket. I said yea, it's French...
Wow did they give him some crap for that
Jacket was by Millet. Great hiking/climbing gear if you can get it at discount.
