I’ve had clear coat fitted to all my iPhone over the years, due to the cost of the phone it’s worth it to protect it with a top quality cover The clear coat protects well and adds little to the footprint of the phone, some iPhones I’ve had the coat renewed several times some not required, it’s good to know for a fitting cost, you can have a re-coat, wether it’s pealed or just a little tatty due to wear. My I watch 6 coated from out of the box, looks great, I watch 4 l worn it for a few weeks before, scratch resistance very little, l had the 4 coated, covered the scratches on the face. Again clear coat adds nothing to the watch foot print, l have replaced the coating (full watch) several times due to peak but you have to expect your going to knock the watch face many times in use. Re coat small fee the watch looks brand new again, l waited best part of a year over lockdown with part peeled face, well worth the wait rather than replacing with Amazon buy All the coats l have had fitted to watch or phone all top quality, my next iPhone upgrade will be straight from box to Mobile Outfitters + your old phone will be mint con when sold on
