Sorry ! - but why are you using it as a base? with Solvaset, MicroSol, Decal1 and Decal2 you have everything you need. After the decals have dried off completely it can be a good idea to 'set' with Future with a minimum overlap to protect against any adverse reaction to a lacquer but I don't know why you should want to use it as a base.
Have I missed something here? M
