MRP (Mr Paint) spidering/building up
Posted by davenport49 on Tuesday, January 24, 2023 10:34 AM

I need to airbrush small, irregular but clearly defined patches using MRP laquers.  I've been running numerous test in preparation, with poor results.  My airbush has a 0.2 needle, and I've tried air pressures ranging from 5 to 30 p.s.i.  No matter the set-up, I get spidering that spreads all over.  As I try to fill in an area, the paint builds up to have a very distinct rough texture.  I tried adding a little Mr. Color Leveling Thinner, but that hasn't helped.  Does anyone have suggested solutions?

Can you post pictures of what it is you're trying to accomplish?  Its difficult to give you advice without being able to see a clear visual example.

The link takes you to two tests.  You can see the spidering as the paint spreads.  And because it dries almost instantly, when you go back over a spot, the layers quickly build up to a rough texture.

If you're talking about the yellow paint, it looks like you're putting on way too much paint all at once.  MRP paint is extremely thin, right out of the bottle, so adding thinner to it is only going to aggravate the problem.  You have to slowly build the paint up in multiple passes, rather than trying to get immediate coverage.  Have you tried just getting the feel for painting with it, without being concerned about keeping it inside a defined area?  MRP paint worked really well for me from the start because I have always painted using extremely thin layers in multiple passes.  You have to be very light in the application.  I would recommend practicing with it on some plastic spoons that you have primered.  Beyond that, unfortunately, I can't give more detailed advice because I have always used a single-action Paasche H airbrush.

I appreciate the feedback.  I concur with your description of MRP, and I like it for broad coverage.  You're probably right in your assessment of my problem.  Trying to get it into those small irregular patches is the challenge.  I'll dial back the flow and keep practicing as per your recommendation.  I just hoped there was an easy fix!Bang HeadCryingConfused

Don't worry.  Once you get the hang of it, you'll still be able to do everything with MRP paint that you can do with others...for military models that is.  It definitely dries too quickly for doing automotive model paint work.
