…except for the spray-paints that I color-matched myself (…comparing colors by eye in the Home Depot spray-paint isle), the basic replacement-shells were bought online (Amazon) …for the white ones, I just used the “White” eXtremeRate “Soft Touch” front & back replacement-shells …combined with the “White” BASSTOP SL/SR buttons & middle-battery-trays (…so, no painting necessary for the “White” ones) …for the light-blue ones (…like in the picture) I only had to color-match the “Heaven Blue” eXtremeRate “Soft Touch” front & back replacement-shells, (…spray-can shown …in this brand, color “Aqua” is perfect match! …IIDSSM) then paint & clear-coat (matte) the SL/SR buttons & exposed part of the middle-battery-trays (…as the SL/SR buttons & middle-battery-trays are usually, by default, “Black”-plastic in most of the eXtremeRate replacement-shell sets) …I only painted the exposed part of the middle-battery-trays (…the separating-stripe-of-plastic between the L/R buttons and the ZL/ZR triggers) since, as implied, these trays hold the batteries internally and paint doesn’t seem like it’d be good in-direct-contact with a heat-prone battery.
…SO!, to answer your question (…after a long-winded explination) …IMHO, the “Soft Touch” texture of the eXtremeRate shells is as-good, if not, better than the Official Nintendo Joy-Con! …they almost feel like the silicon protective skins you can get! …and, so far, the painted parts still look great and the shells haven’t shown any more ware-from-use than the other Joy-Con I own …aside, I’ve taken the time to color-match (…in the same brand of paint) three more of the eXtremeRate “Soft Touch” colors (“Light Violet”, “Mint Green”, & “Sakura Pink”) …so far, I haven’t bought actual Joy-Con sets to convert to these new colors yet (…replacement shells don’t come with the inner-electronics, ICYDK) …but, I would be happy to take pictures of these unbuilt ones and post …if anyone is interested.
