I played around with Zaino a few times, along with Duragloss. Can't tell a difference between the two and the look is fine but doesn't blow my skirt...
The last time I purchased drivepur it was $100 for all of the bottles and it was all used on the interior of one car. Maybe the pricing is different...
Hey John, just wanted to say how much I have appreciated all of your assistance through the last year+. You really are great person and a hell of a detailer!
