Plasti-dip as liquid mask

[Lunajammer]

Has anyone tried this? Results? Recommendations?

That stuff is pretty thick isn't it ?

Try elmers glue as a masking agent. Needs to be thinned a bit. Its a lot cheaper also.

The problem I have with Elmers and Micro-mask is if they get spots where it's thin the paint penetrates. Those same thin spots are a bugger to get up too because there's not enough material to lift cleanly.

Mostly I'm wondering if anyone's tried Pasti-dip.

It's been a while since I bought plasti-dip, but I think it may be too hot and melt what your masking. It is also way too thick.

I have a bottle of Mr Hobby Masking fluid (blue liquid) and it has worked well. You do have to build it up in layers. I had some masking fluid years back that was hot pink and smelled like ammonia, didn't like that stuff and was hard to use.

Haven't used Plasti dip

Humbrol Maskol in coats I've used.... smells like ammonia and is now mauve

works pretty good

Elmer's, water, a drop of dishwashing liquid and perhaps a squirt of food coloring for visibility makes the most perfect liquid mask I've ever used, and it costs only pennies.

Snake, what ratios do you use for the ingredients? How do you apply it and how do you remove it?

[aurfalien]

Yes this sounds awesome. Also curious what ratios.

[Snake45]

I have no idea about "ratios."

I squirt a large squirt of Elmer's into an old plastc 35mm film thing, and then I add HOT water until I get it the consistency I want. It mixes better the hotter the water is, and it will take much LESS water than you'd think (if you're getting it too thin, just squirt in more Elmer's). You can make it any thickness you want, right up to a semi-gel. I like it about the thickness of thick enamel paint. Several drops of dishwashing liquid (I use Dawn if I have it) breaks the surface tension of the stuff so it flows well and doesn't leave bare spots, and also might help with it removing easy, I dunno, but it works. I add some red food coloring so I can see where I'm putting it. The red coloring will NOT leach or "bleed" out onto white paint--I've tested it.

I apply the stuff with a soft paintbrush, and then rinse the brush out immediately with hot running water--it comes right out. For things like airplane canopy framing, I put it on with a toothpick, and the stuff flows beautifully right up to the frame line. Lovely stuff to work with!

The batch I'm using now I mixed up about 2 years ago and it's still good. If it dries out or something, a fresh batch is only about 5 minutes away.

Thanks for that, Snake. I'll for sure give it a try. Well thought out, with the dishwashing liquid to break the surface tension and the coloring. Genius.

[aurfalien]

Top notch Snake, love it. Thanks man!

Without that, the stuff will have a tendency to "pull up" as it dries, leaving holes (bubbles or craters, if you follow what I'm saying) in your coverage. With it, no holes. The food coloring helps assure you of that.
