OK, first off... I am not lazy. Water tends to dry before I can wipe down my truck leaving water spots. We have some pretty hard water here and the water spots are brutal. The Mr. Clean AutoDry isn't easily found anymore and I was looking for alternatives.
I seen this product on Amazon and was wondering if it would stop the water spots? It says it's for RVs, but a filter is a filter?
Anything else I should see?
