it doesn't hurt to have a few different brands at your disposal ,they differ in ingredients and some work better on certain decals than others.

 some of the older solvents, back in time  use to be really really hot chemicaly like the original solvaset and champs brand  because the decals were so thick back than,.. it would  instantly turn a modern decal into goo.

solvaset have since changed their formula to a much more tame solution.( it really upset the railroad guys too !)

you can still find  old stock in some shops .. it has a more amber color to it ..so keep an eye out  and snatch some if you find it

It will lay those Tamiya decals down no problem.Champs quit making there sol several years ago.

but it may still be around in some shops gathering dust.It's so strong that most people diluted it !

microsol  is not bad, it's acetic acid, but multiple applications can sometimes help.

it doesn't have much effect on Tamiya, the newer solvaset works a little better on those.

bottom line - it's good to have a range of sol weapons on hand they all vary in composition and strength
