I will be prepping my car in the next week for what seems is going to be another harsh Michigan winter. Last year, I layered numerous coats of Blitz before and during the winter months, when the weather allowed. The paint still felt and looked very good when spring came along. My question is this, are most of you people layering the carnauba waxes or going with a more heavy-duty sealant? Thanks :xyxthumbs
