Give them a call tomorrow. I am sure you can work something out with them. The one time i had to return something they e mailed me a label and than sent me back the the new one.
I have a Columbia River Knife & Tool (CRKT) M16. Love it I have had many different knifes over the years and i keep on coming back to my CRKT. Also i have a Kershaw and they make a great knife also.
First off welcome to AGO. I have not worked on a car with a clear bra so i dont have any first hand experience. how ever check out this thread, mike has talked about this before but maybe he can chime in and add more later. hope this helps you out a little.
Clear bra care
I have blue velvet, hard candy, and have used purple haze. I think they are all great waxes! If you are not sure about what one to get, get the sample size. I know they sell them on there own or you can get multiple in a value pack.
If you can find AutoGlym HD a lot of people seem to like that, i know others have found it at walmat to of all places. As far as other OTC wax/ sealants NXT 2.0 works well.
