Advice wanted on protective clear coats

I must have at least 50 models where I  used MM flat lacquer over cured Tamiya acrylic paint. The last one being my 1/72 HMCS Snowberry, a long and intricate build where I wouldn't have chanced it if I thought there was any chance of disaster.

I use both Tamiya acrylic and MM enamel, and as long as both are fully cured I have never had a problem.

I had never heard of the "opposite" theory. I doubt if enamel or lacquer will work over acrylics.

Anyway, over enamels I usually use Testors Glosscoat or Dullcoat. I have also used thinned polyurethane varnish for a glosscoat.

I have been using J.W etc Right Step for a while now.  It's a water based acrylic varnish, comes in matte, satin, or gloss, and can be brush painted or airbrushed.  When airbrushing, I cut it about 50-50 with distiled water. 

Dries rock hard and crystal clear.

Like many modelers, I use Future for a gloss top coat & Polly Scale Flat for a flat top coat.  Both are acrylics, but can be used safely over cured enamels or lacquers.
