Decals on top of Decals

i would put the micro set on the plastic first,  hold off on the Micro Sol until last.   put decal 1 down.  get it in place and press firmly with damp paper towel or q-tip.   then go ahead and put second decal down.  Now you can use the Micro sol.    You may want to let the first decal dry a few minutes before second one.  You don't want to risk tearing it or moving it when plopping down the second.

also I am convinced Micro Sol needs to start being distributed in a small fat bottle rather than tall narrow bottle.  i have officially spilled 3 bottles of this stuff all over my work bench.   Nothing like a vinegar smelling workbench!

I have bought decal  brands that are limited in the colors printed.  In these, the decals are made in several layers, so you must STACK them to get the completed insignia or whatever.  So decals over decals is quite common, and no need for worry. I have never had any problems using setting solutions with these.  However, I would hold off on solvents unless absolutely needed.  But this is the same rule I use for single decals.  Setting solutions are pretty benign, but decal solvents are pretty drastic, especially something like solvaset.  Don't use them unless you need them.

Yes quite common,not a big deal,I let one dry a little,then slide the 2nd one on,then I use the Micro sol

I usually put down the Future, let it dry, place the decal, let it set then coat with future to seal. After this is dry, I set down the second decal on top, let it set and then coat with Future. It works great and I've had no problems with this process. No other solutions needed.

Hope this helps.

I've done this a few times, but unlike the other posters, I've let the bottom layer decal dry completely before adding the second or subsequent decals.

Very common practice. Just let the decals set and I prefer for them to be dry before putting on the next one. A lot of people don't wait that long but I usually wait at least an hour or so just to make sure I don't accidentally move or mess up the first one.
