The last 2 times I applied UPP (original I presume, because imy bottle is about a year old now) to my truck I ventured into unknown territory. I began with a dime sized dab on a 4 inch yellow foamie. Then hit that with 2 full spritzes of EO Wipe & Shine. Next I folded the foamie in half to distribute the juicy mixture all over the pad. It went on easily and most importantly very thin. Rather than let it sit the recommended hour, I wiped it off with a dry MF as soon as it hazed up. (a WO-WO variant). Final wipe was done with a DF MF towel. No problems with streaking or stickyness. Just a brilliant, super slick shine.
Works well in direct evening sun and temps about 85 degrees. All that seemed to do was cause it to haze a little faster.
I decided to try this method with UPP since it is an acrylic similar to the KLASSE twins. CMA recommends spreading AIO with EOWS, so I figure what-the-heck go for it. I'm very happy with the results and given the fact UPP doesn't need to seup for an hour or so before buffing off, saves boocoos of time as well.
