Now I know why Bandai dont include etching decals with their kits and instead include gross looking stickers which spoil your work. The reason is that they want to make money from their line of
water transfer decals (refresh that link if you dont see a ton of water transfer decals) which are sold separately. These type of decals have to be soaked in water and transfered off its backing sheet onto your kit. I didnt know these existed for Gundam kits until I saw them in my local hobby store - I'll be sure to use these next time though. If you are using Top Coat - be careful which type you use as there are Top Coat varieties which dissolve these water transfer stickers! (you will have to read the label on the can to find out. If you are ordering online - ask the seller).
