That is a good idea! Rvs, boats, rigs. I don't know that could be pretty good too! I thing I thought would be nice to is a holder for the sponge. The sponge is very soft and needs an abrasive surface for bugs and what not! My degreaser sponge was the pet sponge form and gave me know way to get stubborn dirt off, needed to use a toothbrush.
