I guess you can look it that way Arcee. Although as HD mentioned you can still use the method if you need to remove a good stickers (like in G1 deco Tfs) momentarily and "apparently" once it dries you can still reuse/re attach the sticker. e.g. if you found a Tf you wanna improve the white (using the H202 bath method) and the stickers are in the way but are quite good enough you dont wanna buy replacements, you can peel this off to reuse later using the Zippo method. Best to look up his blog fpr details, not sure where it is there , but the blog is quite interesting especially if your a toyhunter in overseas places and like looking at vintage , pristine G1 stuff
