Why Mr Color Leveling Thinner Is Necessary
I’ve found that Mr Color Leveling Thinner is necessary because it gives me a much smoother finish than regular thinner. When I use it, the paint seems to flow better and level out more evenly, which helps reduce brush marks, spray texture, and that rough, dry look I sometimes get with other thinners.

My experience is that it also gives me more control over drying time. Because it slows the paint just enough, I have a little more time for the surface to settle before it sets. That extra working time is especially helpful when I’m airbrushing, since it helps prevent grainy finishes and makes blending easier.
I also like that it works very well with Mr Color paints, so I can trust the result more. For me, it’s not just an optional add-on—it’s something that helps me get consistent results every time. If I want a smoother, more polished finish, I feel Mr Color Leveling Thinner is worth using.
My Buying Guides on Mr Color Leveling Thinner
What I Look for First
When I buy Mr Color Leveling Thinner, I first check whether I need it for airbrushing, hand mixing, or improving the finish of lacquer paints. I use it mainly because it helps paint flow better and levels out brush marks or spray texture. For me, the biggest benefit is the smoother finish it gives on models and hobby projects.
Why I Prefer It
I like Mr Color Leveling Thinner because it contains a retarder that slows drying a little. In my experience, that extra drying time makes a noticeable difference in how smooth the paint goes down. It also helps reduce orange peel and gives me more control when I’m spraying fine coats.
Compatibility I Always Check
Before I buy, I make sure it matches the paint I plan to use. I use it with Mr Color lacquer paints and other compatible lacquer-based hobby paints. I would not choose it for acrylics or water-based paints unless I know they are specifically compatible. Checking compatibility saves me from wasting paint and thinner.
Size and Value
I think about how much I paint before choosing a bottle size. If I am working on a few small models, a smaller bottle is usually enough.

How I Use It
When I use Mr Color Leveling Thinner, I usually mix it slowly into the paint until I get the consistency I want.

I also keep my workspace ventilated and use proper protection since lacquer products have strong fumes.
Things I Watch Out For
I always pay attention to the smell, drying time, and storage. Since it is a lacquer thinner, I store it tightly sealed and away from heat. I also avoid over-thinning because too much can reduce coverage and make the paint run. In my experience, a little goes a long way.
