again, no one is saying that synthetics won't outlast carnubas. And who cares if you have to rewax every month, we are all doing it anyways. If you don't take that great care of your car a synthetic is the way to go.



If i'm not mistaken, Guru Reports 2001 test was done w/ mid 80 degree heat and the products were all left outside so I assume they all saw some good direct sunlight. If so, why didn't all the carnubas fail after the first week?



I was hoping my rejex would of been here by this morning for my dads 745li detail, but it didn't arrive so I went over w/ p21s. Results are great. He lives where it's 90 degrees during the day so we'll see how it lasts. Figured it'd be a good experiment

 

Guru Reports wax/sealant shootout was in 2002 I beleive. The testing was done over the course of 8 weeks so I can't see how one can say it was "mid 80's". I'm sure the weather/temperature varied quite a bit over the course of the study.

 

I thought I remember them saying that, it may of been the latest test they did.
