I wanted to see what everyones take on this subject is. I have yet to really be 100% confident with a vehicle prep degreaser/ APD that i love. The p21s is great but expensive, and im looking for something that pretty dilutable. We do alot of cars/ day because that is just the type of business that is most common around here. Consider it alot of production detailing. We have 3-4 really high end clients a week that get the full "boutique" treatment but in the meantime until we branch off and separate the 2 completely, i need a product that is not only cost effective, but does a great job degreasing door jambs, cleaning engines, loosening up bugs on the front end of vehicles, and also a possible APD for vehicle interiors (minus leather). Again this is mainly for dealership vehicles/ retail clients that just want a good detail without the cost or attention of what vehicles truely need. We have been in business going on 5 years now and are averaging 8-10 cars/ day so we are BUSY AS HELL, so any info would be great... i would love a go to product!!! BTW....please dont think were a hack detailshop...lol. We have 2 rupes (15 and 21), use alot of sonax and menzerna products, but would never use these to touch a lease turn in honda civic unless they are paying for it lol. Its just the nature of the beast around here.
