Masking Tape Leaking -2 tone Paint Job

[69NovaYenko]

Have a heck of a time doing 2 tone paint scheme. What tape/techniques are you guys & gals using to mask off your  bodies

[Michael jones]

Use tamiya tape or washi tape. Cut a fresh edge with a sharp knife and burnish down. Then spray a light coat or two of the base colour or clear coat of the same type of paint to seal the edge. Then spray your second colour over that.

Greg,

Why don't you let us know what tape and paints you are using, and what is your masking/painting  technique?

You said "Cut a fresh edge with a sharp knife." Is the he manufacturers edge prone to leaking?

And  no I haven't tried spraying a light coat or two of the base colour or clear coat of the same type of paint to seal the edge.

Ya ..I have found that blue painters tape doesn't work well when spraying paint on model cars. Tamiya tape works best for me, and a quick shot of clear or base colour seals the edge of the tape like Michael said.👍👍

Sometimes I use BMF to mask some things..... I would use the foil to make the "edge" then use masking tape for the rest. That way you're not using up all your foil........

That's probably one of the worst tapes to use for masking edges.

It's literally designed not to stick very well.

Second worst tape to use is regular masking tape.

It sticks too well, but still does not seal well enough on the edges, plus it has the tendency to leave residue behind and can even tear off the underlying paint.

 

Tamiya tape is your answer.

I recently did these stripes with Tamiya tape and all that I did was cut a clean edge, apply it, burnishing well on the edges and then apply light coats of paint.

It will give you perfect lines if you do it right.

i always do a thin coat of clear coat first. this way any leaking that goes under the tape will be clear. 

[MrObsessive]

I swear by Tamiya Tape! For doing stripes and such as what Steve showed on his Dodge, it's pretty much the best stuff to use. Here are stripes I did on my '05 Mustang GT. The clear stuff is Parafilm to mask off the rest.

The suggestion of using clear coat along the edges is a good one. Another choice I've used in the past for masking two tones (or black trim around windows) is BMF. Expensive, but you'll get a super clean edge with nary a bleed under if burnished down properly.

Steve's correct on all counts. His work speaks for itself.

Blue tape is designed primarily for water base paints on things like walls, where its relatively poor adhesion helps prevent it from tearing poorly adhered undercoats off the surface.

Regular masking tape isn't designed to do crisp edges.

-----------------------------------------------------

One other method: 3M fine-line green plastic automotive tapes, made specifically for obtaining clean color separations on flames and graphics using solvent-based paint.

EDIT: One thing that's absolutely imperative for getting good two-toning is to make certain your base color is adhered very well to the surface.

Masking over poorly-adhered paint will guarantee failure.

I wonder if that new crappy BMF would be sticky enough for masking purposes? If one already has some and can’t return it.🤨

I bought some Tamiya tape and it couldn't get it to stick to the paint on the car.

A fresh edge is cut to get rid of any crud the tape may have picked up sitting on its side. Lay a strip onto a piece of clean glass and trim the edge with an exacto blade, using a straight edge steel scale or ruler.

That’s totally uncharacteristic.

I’ve used dozens of rolls of Tamiya tape and have never had adhesion issues. 
I’d be interested to know the particulars of the paint that it wouldn’t stick to.

Otherwise, you were unlucky enough to receive the only roll of bad Tamiya tape on the planet! 😁

Like others, I'm really surprised.  I never had a problem with it adhering.  Silly question: you didn't happen to wax the paint you were masking?

Tamiya tape is rather pricey -- "Washi tape", which is available in craft stores or online is basically the same as Tamiya, but less expensive.  Still pricier than regular masking tapes, but well worth the extra cost.

[Plowboy]

The blue painters tape can work. But, it has to have a cut edge and be burnished well. The scallops on this '37 were masked with a single piece of 2".

This Silverado was also done with 2" blue painters tape.

But, Tamiya tape is still better for more simple masking. When you buy it, spend the extra and get the dispenser. No ruined edges or lint stuck to it. Just pull it out and use it.

No. Just a painted model. I was going to use it as a cut line for foiling the side trim on my black 64 Comet. It is now in the purple pond for the 6th time because my foiling damaged too much of the paint. 

And it was the nova and comet that were Duplicolor Black and clear.

I bought a bum roll too a while ago.  It was the very narrow tape designed to curve etc - wouldn't stick to anything for love nor money.

I did notice that it was not made of the same material as the regular tape.  This tape seemed as if it were made of plastic?  for want of a better word.

It's the only Tamiya tape that I've ever had problems with.

That's the one I was using as I had to do a curve.

Tamiya (Washi) tape I believe is made of some bamboo-based paper.  It also does not have very aggressive adhesive. so the narrower the tape is, the less area is on it to adhere, and it will make it appear not to be very sticky.  I would not expect very narrow strips to stick very well to anything.  That is true about any masking tape, but if the tape has a more aggressive adhesive to begin with, the narrow strips will also have more "stickiness".

[SCRWDRVR]

I worked in body shops for years and use fine-line tape like above, there is also a blue version of it that I am not sure if is made by 3M but it is a little more flexible for those tough corners...

The very narrow tape that I bought (that wouldn't stick to anything) was not made out of the same material as their wider tape.  Understandable too I guess since it's designed to curve but apparently not designed to stick LOL

Anyone have a recently purchased roll of the very narrow Tamiya tape?  Is it still the flexible plastic or have they changed it?  And more importantly...does it stick?  LOL

Be careful when using blue painter's tape or regular masking tape. Some are not recommended to be used with lacquers or polyurethanes. Read the inside of the tape roll to be sure.
