What type of wash to use on enamel (Testors MM)?

[Edbert]

I'm seeing success in applying Tamiya or AK washes, but I understand they are safe to apply to Tamiya acrylic (XF) paints with or without a varnish.

My question is, do I use a diluted Tamiya XF as a wash on top of a new gloss coat of Testors Model-Master insignia white?

I think the answer is yes so, followup...do I dilute the XF wash with X20 or something even milder like water? I think the hardened enamel is close to bulletproof but I dunno, so I ask.

Not too sure i know most of these products are perfectly safe over acrylic paints but not recommended over lacquer paints ,what are testors I'm sure someone will give their answer to this hopefully not learnt the hard way. Dave
