actually there is a product for aircraft leading edge de-ice boots that will strip and re-coat rubber products and leaves a hard, durable, perfectly smooth nice shine, which can be cleaned without stripping the coating off.
BF Goodrich makes a version of this product, as does Boots Edge. If you search for de-ice boot treatments, you will probably find something really good.
This stuff is far better than the armor all type of products. Not even in the same league.
