as far as silicone goes, they all look and feel pretty much the same, the difference is the chemical additives they have in them. If you want something even better than the AFM you can just get food grade silicone or aquarium grade silicone that wont have alot of the bad chemicals that caulking has. They are usually called sealants instead of caulk.

and all silicone gets dirty after a while, I have one I’ve been testing for over a year now in the bottom of my purse and on a charm and lets say its kinda grey lol. I usually use clay but when I do use silicone after its fully cured I give it about a week to 2 weeks sometimes I coat it in resin to keep it white and not dirty. It wont be flexible anymore but it’ll look the same at least.

You’ll just have to find what works best for you. I like things to be very neat so I always look at all the details since I sell my products other people may not want to do all the extra steps I do so its usually best if you experiment.

Thanks! I love your blog. It’s very cute.
