Can you use Hybrid Wax as a base, and apply another wax over top

No, this is meant to be used as a Last Step Product. We recommend using our CarGuys Liquid Wax as a base, then applying this over top. The special polymers in this product sometimes don't mix well when applied on top of other waxes/sealants unless it's a full synthetic polymer such as our Liquid Wax. However, if you were to try applying our Hybrid Wax Sealant as a base, then applied that product over top, we would love to hear your results so that we can pass this information onto others in the future!
