Blasphemy, I know. But I've been using the Bob Ross Titanium White, and while the thickness is really good for mountains, has anybody else noticed that it might be too thick to use for other things??? Having difficulty with clouds and putting highlights on trees and bushes because of it leading to mud mixing. I've tried thinning it with a little paint thinner, but even just using a little makes it too thin in my opinion. Anybody have a similar experience?
