If you can read the instructions on the bottle you've either found a bigger bottle or have younger eyes than me!
Micro SET you use like the Testors, soak, dab, apply MicroSet and apply decal.
I find the SET is too agressive, so I don't use it anymore as I have a hard time sliding the decal into the correct position. I use it only for moving decals that have already set and dried. With varying success rate. Sigh!
Micro SOL is used to snug decals over uneven areas. You paint the SOL on top of the decal once it's positioned and dried into place. Beware it wrinkles up like a prune, but believe it or not it will dry flat again.DO NOT TOUCH THE DECAL once it's applied. It will shift, fold, tear, wrinkle and fall off!
I find that if you're heavy handed with the fluid it can cause a Future gloss coat to fog up, which may or may not go away depending on how much fluid and how long you've left the fluid on.
