Great product but watch the smell

Bought for my waterproof pairs Caterpillar, this product works well and prevents the appearance of spots and places darkened by water. But during application, it must be very careful to do outside because of the smell that will remain in your nostrils for a while, rather unpleasant odor. But on the other hand I do not think there is a waterproofing that smells the rose during the application! For now I have applied twice on my two pair and there is still quite a product!
