Default Good masking technique

This ideas occurred to me after watching a frog tape commercial, and I was wondering if anyone had tried it, and how successful it was. After masking off an area give that area a light cost with a clear spray. I think this would seal off any possible bleed under along the edges of the tape. After that coat was dry go back over it with the intended color.

That's a pretty old technique...

You can spray clear to seal ANY tape edge, or better yet, a quick light coat of the same color that you're masking over... that way any bleed-under is the same color as the paint you're taping over.

Correct that "frog tape" is formulated to seal best with water-based paints.

Yes, I've heard of that technique and several different ways of going about it.

Tamiya masking tapes are the answer. Press the edges down good and you won't have bleed-under.

I've read about the same color and clear coat technique and my question is how long do you wait before applying the top coat? You don't want the edge sealing undercoat to totally dry before applying the topcoat, do you?

I don't know. I do know that I let some paint dry for about an hour and a half before taking off the tape (got distracted) and it lifted the edges when I took it off.

To be honest, I'm not a fan of "paint sealing" tape edges. I'm sure it's just me. Besides, I wouldn't want to build-up an edge where colors meet.

I usually paint seal tape edges to get a clean edge. I usually use transparent base to do the sealing, just painted on with a fine brush at the edge. This is with airbrush acrylic paints. Back when I used rattlecans, I would either spray a light coat of the base color as described above, or I would spray a bit of paint into a cup, and paint it on with a fine brush at the edge.

I find this to be a quick way to ensure a clean line.

As to drying time, it depends on the paint. Airbrush paints I let dry an hour or so after sealing, with lacquers I would also give it at least 30-60 minutes after sealing before putting on the next color.

I'm not a fan of using a rattlecan clear paint sprayed on for the sealing.... I don't want to create a layer of base, topped with clear, topped with color. I can't say this causes problems, I just don't like the idea.

I spray a coat of the base paint over the tape and wait probably 3-5 minutes before laying down the overcoat color...it takes me that long to shake the next can, attach the spray can handle, etc.

I always pull up the tape as soon as I'm done laying the paint down. If the paint dries/hardens it will almost always pull up at the edges when you remove the tape. Have heard of some cutting through the paint with a razor blade to prevent that but immediate removal of the tape is the simplest solution. Just be careful you don't touch the fresh paint with the tape or anything else.
