I know that when you layer a wax you should wait at least 12 hrs. befor applying anoher coat. I recently read something in the Griots Garage catalouge about layering wax. He said to apply a layer. wait for it to dry, then apply another caot ontop of that one and then buff out. What u guys think about this....wouold save time but would the forst coat have time to cure? -Brad H
