I used quite a bit of VM this year. It is one of my favorite products. I like the versatility of the product (use it on paint, glass, plastic, smooth trim, chrome, etc.) and the glossy appearance it leaves behind. I don't really have any dislikes. I only have one point of concern and that is a potential durability issue with follow-up sealants due to VM's oils/fillers content. This is not a worry for my personal vehicles as I can detail them whenever I wish. However, I do have some trepidation about using VM + sealant combos on vehicles that I will not be able to maintain regularly.
Earlier this year, I experimented with various base coats for Poorboy's EX and EX-P sealants. During that time, I observed that SSR1 and VM produced very similar looks. When used with polishing pads, VM looked just a little better to my eyes but very close. However, when I tried SSR1 with a finishing pad, it was virtually indistinguishable from VM. Because of this finding, I have decided to go with a SSR1 + EX-P x2 combo this winter for my daily driver. It is my hope that durability will be greater with SSR1 as a base coat (no oils/fillers) than VM. We shall see.
