A new tape and my technique for taping

Postby ShotgunDave » Thu Mar 02, 2017 7:18 pm

I have to admit to stumbling onto this product by accident. A few months back, I had to do a repair on our furnace. After re-assembly, I needed to tape up all the seams again. I went to Lowes and the gentleman there suggested this tape. It is 3M part number 3350.

Image

It's made from an ultra thin mylar plastic. (at least it feels that way) It worked great on the furnace but I didn't need nearly as much as comes on the roll. And it's a bit pricey too, it cost almost $12.00 for the roll. So fast forward a bit, I was masking one of my cars for paint and realized I had run out of regular masking tape. I didn't want to drive all the way to the store, so I grabbed this tape from the shelf and gave it a try. I was pleasantly surprised! It sticks well and comes off just as well and DOESN"T pull the paint from the previous color off! It also comes off clean, meaning it doesn't leave any glue residue behind.

Now here's how I tape up a model. Once I get the first color on and I'm ready to reverse mask for the second color. I get out my acrylic board, straight edge and X-Acto knife.

Image

I peel some tape off the roll and place it down on the board. If I'm going to make a curved line, like I did on this model, I cut a piece of the tape about 1/8" wide. That's thin enough that it will curve without kinking. Here's how it looks on the model.

Image

Once I have that laid out, I cut some small strips to fill in the area I want to protect.

Image

Next, I spray a light coat of clear on the area to be painted and let it dry. This keeps the second color from bleeding under the tape. Once dry, I spray the second color on.

Image

Now it's time to unmask. Gently remove all the fill in tape then pull the outline tape off.

See how crisp the line is? That is right after the tape was pulled. No touch-ups.

Image

And here it is with decals and clear on it.

Image

I know the tape is expensive but it's worth it for my models. Besides, there's enough tape on the roll to mask off hundreds of models.

The clear coat between colors is a great tip. Thank you so much for this!

bigman, I spent 40 years of my life as a professional auto/aircraft painter. I was actually involved in the testing of that green tape when it came out. I love that tape. If you are having good results with it, I wouldn't switch. Like I said, I found this stuff by accident basically because I was lazy. :lol: But I will say this, this mylar tape leaves the crispest, cleanest line I've ever seen. You can take that for whatever it's worth.

You're welcome Val, glad to help. I have to say though, that it wasn't my idea. Someone else here on the board recommended it and I tried it. I wish I could remember who it was so I could give them credit. I really does work great.

:text-thankyouyellow:
Dave Thank You For your reply, :text-bravo:
I to love the 3m green tape, it's all we use in my shop. :auto-driving:
I was Involved in building custom cars for years plus we worked on cars at home all the time. :teasing-blah:
Sometime you just fall into a new product or something different and it's better then the stuff you would have normally used. :idea:
:o I'm going to look into the 3M # 3350 ultra thin mylar plastic tape. :auto-checkeredflag:
It all about the details, crisp clean lines is a good thing and if it leaves the paint alone even better. :text-bravo:
Thanks Dave for this post :text-thankyouyellow: , You can teach a old dog new tricks and HRW is the place to lean alot of cool thing. :auto-driving: :auto-checkeredflag: :auto-driving:
