I was impressed with its cleaning abilities while leaving a shine. My guess is the finish would last longer if I now applied a good wax. I just ordered and recieved the Collinite 925, I think that was the number , came in a quart size bottle. It looks pretty easy to use, I tried an area on my truck and it went down easy and came off easy. Is there any other Collinite products you would recommend? I did order 2 more bottles of 870 already, that stuff works great in my opinion.
