The kids love using mine as a skateboard. I'm happy to see it used for something considering few people in albuquerque are willing to pay $2.50 -$3.50 s/f for color sealant. Heck, that reminds me of a free demo i did in the middle of a lady's tile living room. Then i gave her the a quote on the whole job and never heard from her again. I bet to this day she still has a big beautiful giant Grout Perfect X in the middle of her nasty living room grout. oh man! what do you do? I just don't offer the service anymore.
