Global Scale Modeller

Hi there,

I noticed recently that enamel wash causes white spots on my varnish coat (is it so called frosting?). I think this isn't supposed to happen. My steps are:

- primer
- base color
- varnish (flat clear)
- applying enamel wash
- waiting ~1 minute
- washing off with a brush / cotton bud

Do I miss here something?
Take a look at my experiments:



TS-80 - Tamiya's Flat clear
TS-13 - Tamiya's Clear (glossy)
34102 - Revell's Flat clear
34101 - Revell's Clear (glossy)

Should these white spots be there?

I have absolutely no idea mate, what colour of wash were you using?

What thinner are you using for your matte coat ?

It looks to me that you are rubbing thru the top coat along with a reaction between the products, especially on the Tamiya coat as they are lacquer based. What type is the primer and base color, acrylic/enamel/lacquer? You want to make sure they have cured (longer than dried) before putting a clear coat on. if you are using solvent based washes, like enamel, you need to have an acrylic clear coat that won't react to enamel and the thinner. I use Alclad Aqua Gloss, it's water based so you shouldn't get reactions. https://www.megahobby.com/products/alcl ... ottle.html
