After doing a couple of cars with EX and EX-P it always seems that unbuffed spots of product magically appear after a week or day of rain. I got my cousin the VM/EX combo from SMP and we did his Explorer and Jimmy; and both cars within a week had the product appearing everywhere. I helped him with the Explorer but he did the Jimmy on his own. I also did his father's big Super Duty with 1Z PP+EX, and I noticed tonite spots of EX all over the place. I remember really checking a couple of times with the Super Duty too. This has also happened with my mother's and aunt's car. I just want to know if anyone is experiencing this?? I've used S100, CMW and WG before and never ran into problems like this. As of now EX and EX-P are "quarentined" from customer's car, if this residue keeps occuring.
