Making decals slide better

A lot depends on the decals themselves. Some stay where they're at and don't want to budge. Use plenty of water, with some dishwashing detergent added to break the water tension, before laying the decal down.

Sliding the decals on the model into position.

A little bit of water is all you need.

Just water,sometimes the set or sol slows them down,apply after you set the decal where you want.

I know several folks who use warm water to help make the decal slide sooner and better.  I bought a little heating unit, but find I personally do not use it that much.

The newer, thinner decals do work much better when you slide them into place rather than picking them off paper with a tweezer.  They are so thin they tear easily, and placing paper near final location and sliding them into place reduces breaking and tearing.  Putting setting solution around final location makes the decal slide over the model better, once it comes loose from the paper.

The directions on just about all decals say to use warm water.

I have found the opposite that the solution causes the decals to stick before I want it to,so I only apply solution after I have it placed right where I need it.

Another vote for this method. It's what I do, anyway. Just one drop of liquid detergent in your decal soaking tub of water is plenty.

We need to differentiate between setting solution and solvent solution.  The setting solution is merely a water wetting agent and should not make decals stick more, though it helps them nestle down.  Solvent solutions, though, do make decals stickier.  They are not the same solution- be sure you know which you are using.
