Masking 90 Degree Corners for Stripes

First time striper (not stripper) here and new to the board...

I will be laying out some stripes on my 67 Mustang this weekend and have discovered that I need to get my masking tape to make a few 90 degree turns. My only thought here is to cut the tape, turn 90, overlap and continue.

Any helpful tips here?

The pic is to show off a little and the next time you see her - Rally Stripes!

Great Board by the way,

Ride On,

Noel

3M brand fine line tape is a must! It will make a tight bend. Another trick is when you get it all laid out and have your paper on it, go around and make sure that all of the tape is still stuck down, checking all of the corners.
Buy a roll and practice laying it out before you do the actual job.

I agree 3M has the best tape and the blue is the better one for making tight turns it doesnt lift as bad as the green

why cant you cut the tape on a piece of glass then peel it and put it where you want it. Then all you would have to do is the tape up to and leaving the curve. Now remember I am not a bodyman ,I can barely paint a house.Just a thought.

well I guess you could try that I never have but it seems to me that you could have paint bleed thought where the corner meet the straight peace

Thanks folks,

I am currently using/practicing with the 3M green fine line tape and have noticed that it tends to stretch and thin when making tight curves. Not too big of a deal, I think I can pratice that out. My main concern is making a strick 90 degree sharp corner. I am basically needing to make a "T" with my tape. If I go this way, I will end up with tape overlapping which, in my unexperienced mind, could leave a line where paint can bleed to - where the tape leaves the paint surface and continues onto the adjacent strip of tape. Similar to what latech has descriped.

Hopefully I'm making more of this than necessay, but I had to ask for tips. I plan to use my fingernail to get the tape to mesh as tightly as possible and try not to lay the paint on too wet on the first coat. I'm covering bright white with jet black.

Ride On,

Noel

I have to tell you my experience has been that none of these tapes bend a tight corner well. Well let me put it this way, it will make the bend but it won't stay down long enough to get the painting done!

Tape is cheap (well, it's cheaper than re-dos) so tape out what you plan on taping and let it set as long as you figure the painting will take. Tape it out tonight (obviously not the whole thing, but the critical areas) and let it set until tomorrow. Look at those corners and see if the tape has pulled up. If it has, you need to do something different. If it hasn't, then you are good to go.

I have found that cutting and overlapping is the only way to do real tight curves.

The 1/8 blue fine line works good. Just keep the temp around 70 to 80 and it sticks good depending on how tight your laying it on. When the temp changes is when it starts to shrink back somewhat but it can be done, not to hard.
It is obviously a technique can you get a piece of tape and lay it out and explain how you make those curves? Are you stretching it a little as you push it down? Or are you letting it "gather" a little as you push it down?

I have done VERY little custom paint but always seem to have a problem with that tape pulling up on the corners. I will press it down and run my finger nail backwards across it like a "squeegee" when putting a large decal on. If that makes sense. I have had the darn tape come up just about every time I have tried to bend sharp corners. Fine line in blue or green, it doesn't seem to make a difference for me.

Without a doubt if I had taped up that truck I would have had rolled up edges here and there. What are some tricks?

Templates ... I like the American brand name masking tape.
It turns corners better than any other masking tape as far as masking tape turns and sticks to its'self..The blue fine line is also the best for corners and green fine line handles straight lines with ease..

When I mention templates I mean that one would use tape as a guide to the tape that is going to be the mask...so mock up first then put the actual tape next to it instead of trying to put down the stripe in one shot..

I'm with you on the American tape, it IS better than 3M. On the "templates" never thought of that, but I do tape the edge last as you can see in this "Basics of Basics" on two tone masking. CLICK HERE

Milo, I looked at your link and now I am confused. You show the template being made from a tank already painted. I read what I thought was every word, but I don't understand. Did you pull that template off a previously painted tank so you could duplicate it?

I was under the understanding before I clicked on the link that you would mask the tank up then mark the edges then remove the template and then fine line the edges then mask between the fine line. Is that what you did and I just don't get that from the photos? Are you showing the template in the first photos over the white to explain the process but the tank was already painted at that time?

Check out my link as to how I do it, are you doing basically the same thing?

LOLOLOL, ok, I guess that IS what you did now that I look at the photo you posted here, you had another tank already painted. But how does that process help if you don't have that? Do as I thought and just tape it up using the triple masking and remove it to fine line the edges?

Here's what ive learned from doing my truck.


Dont use old tape, Dont use blue tape, Dont use low tack tape.

Tape over the fine line as close to the same temp as it was layed on with new tape only. Yea i stretched the fine line in 75~ temp and taped over that as soon as i could. It took about 4 days to mask the whole thing up. At night the fine line does pull up, i didnt mess with it till it warmed up.The key to sharp curves is the temp and spraying it at the same temp. Learned that the hard way.When taping the fine line you cant rush through it. Yea gota make shure the tape is on there good, i rubbed it on hard and for the most part it stayed.

One last Dont.. Dont let drunk friends help, its fun till the next morning, then your like ,what the hell was i thinking!

Ok, so temperature is a biggie, cool. I know that the NEW tape is a big one. The last thing I taped off was a tail lamp on my Gran Sport for the black and silver stuff they had on from the factory. I had plenty of tape and was having a hard time, I went and bought new tape and it worked MUCH better.

Thanks for the tips.

I think i missed something you were wanting to know.
I used the blue fine line first then taped over it and then masked it all off.
May not be the right way and it was a pita but it worked fine.
Yeah I like having the edge taped last so I can unmask it. I started doing it that way years ago while two toning bumpers for late model cars, it works REALLY good for me. And you can still tape over the fine line if you want to help hold it down or what ever. But as long as the fine line isn't buried under the surrounding masking it will still come off easy before the rest of the masking has to. It works well for me!

Heres a nightmare for yea.

LOLOL, that is BEAUTIFUL if you ask me! I love it, like I said I have done very little custom paint work. But I love seeing it and the passion needed to do something like that is inspiring.

yes, to duplicate and I learned templets from you

Good thread folks, thanks for the replies. Just wanted to conclude with a pic or two and say that my first experience with stripes was rather good. I will also say that when someone says "your tape has to be perfect", they mean perfect. Most any overlapping of tape, wrinkles, loose spots where it pulls up and you push it back down (repeatedly), or splices will show some evidence. Luckily some Q-Tips and thinner can fix it.

The "T" I had to make with the tape is right behind the hood scoop to create the continuation of the thin stripe towards the windshield.
