Looking to try something new, Nanolex looks interesting, especially the somewhat interesting application when doing 2 layers. As for good, better, best it appears that: SiShield = good Si3D = better Si3D HD = best? I also see Si3D BC avaliable in UK. 1. Looks like Sishield is avaliable in 30ml here at DD; guessing that's not gonna cover 2 coats on a panel van...50ml avaliable? 2. Are the others pro-only? Seems to be no restrictions noted on UK site but see no availability here on DD. 3. General experiences with longevity. Properties I look for in a coating: I live in NE Ohio so all ny findings/thoughts are based on that climate. The characteristics of a coating that matter most to me are: 1. Great Self Cleaning Abilities: Our cars see rain and often get rained on in the morning and then sit outside in the sun in the afternoon; don’t like waterspots. I like clean cars but don’t like cleaning cars. 2. Durability and resistance to environmental contamination like water spots and bird bombs. Don’t wanna have to worry about running home and immediately dealing with removing things that would otherwise etch bare paint. Like hard water spots did to our Corvette during the Zaino years. Also has to last cuz I don’t wanna be hauling out compounds and polishes every Spring, given reasonable maintenance. 3. Appearance: Well, stuff has to look good. Has to accentuate body lines, curves and hard edges. It needs to make me stop and admire it when walking towards it, walking away from it or catching a glance in the garage when I take out the garbage. So far, the best I've found *for me* and what is now on all our personal cars are Miyabix2, ISMx1, Infinity Wax and Overcoat from the Kamikaze Collection of products...the stuff just plain works for our situation. But I'm sure you know how it is...always chasing Unicorns. I'm wanting to give this a go on a new Ford Transit E250 that will see limited maintenance going forward; is Nanolex up to a task of this nature? For what it's worth, have tried the below in the past year, looking for something new: Cquartz Classic Gyeon Mohs (with and without Gyeon Booster) Gyeon Prime Gyeon CanCoat Feynlab Ceramic Pearl Nano The Gloss Shop Ceramic V1 The Gloss Shop Ceramic V2 Gtechniq Crystal Serum Light 22ple HPC Wolfgang Uber Ceramic McKees Paint Coating V1 Kamikaze Miyabi Kamikaze ISM Complimentary products/toppers/boosters Gtechniq Liquid Crystal C2V3 22ple Final Coat VS1 22ple Finitura Gyeon Cure IGL Premier Kamikaze Overcoat Kamikaze Infinity Wax TAC Systems Moonlight Gyeon Booster Any info/suggestions appreciated.
