Can't get rid of test spot lines

[1Clean3]

So I was detailing my roommates car today with poorboys ssrs 1-3. I was using a masked off test spot to get the look I was going for. When I moved on with the rest of the panel, I couldn't buff out the masking tape line from the edge of the test spot. Has anyone else had this problem? Any ideas to try?

On the test spot I used ssr3 with about 6 section passes using pc7427 and a 4 inch cutting pad. Then used ssr 1 with a 4 inch gray finishing pad doing about 8 section passes. When I removed the tape I went over the test spot line with a 4 inch orange cutting pad, doing 2 sets of 8 sections passes, and then ssr 1 again with a 4 inch gray finishing pad doing 1 set of 8 section passes, and the lines are still there.

Is this tape residue lines?

That's the downside of the tape-line...

One thing I do is I very rarely buff a lot next to the actual strip of tape. Some paints are harder to remove any line left than others...

Also happens when you use aggressive products and also happens if you keep testing in the same area...

I've had this problem before too and all I've every done is continue buffing on the non-test side around the line to try to level it...

Be careful if this is factory paint...

yep, this is why I dont do test spot's with tape anymore. I etched out a really deep gouge once in my paint that I did not feel safe fully removing. Luckily it was near window trim and on a light colored car. I could feel it with my fingernail. If you buff hard against the tape to show a GOOD 50/50, the pad basically buffs up against and then is forced under the tape (on a very tiny scale obviously. I'm just overstating it to get a mental image of whats going on)

I'm now super careful about taping the car, and when I do, I always tuck the end of the tape facing the paint UNDERNEATH the trim piece.

I have seen a few professional detailers mention this problem on this forum. But its not a hot topic unfortunately.

My first 2 full paint correction jobs I taped off the sections that I was working on and had the same problem. Would spend more time trying to buff/remove the residue and/or tape line back out. Now I just tape off the necessary trim and detail away which ended up saving me a good amount of time per detail.

Thats why you dont use the tape when detailing ever. You buff away so much then you have to buff enough to level the edges. You dont need a tape line to see before and afters.

But, best of luck. I would try buffing a little more on the line to level it.

Yet another reason not to use tape...

The rare times that I do use tape I use 3M 5 day tape

Yeah, it's a bummer.... but.... there are different types of tapes....
The regular type, the brown one... I'll never use it... even a 3M one... used once and regret for 3 or 4 extra hours on the job....
I was using the blue premium one from 3M, great tape... will leave little residue and won't be eaten by the machine very easily...
2 weeks ago I was detailing outside of my city and I couldn't find the blue tape anywhere, but fortunately I've found the green one.. the 3M 233, which is way cheaper then the blue one.... but to tell you the truth ? I didn't like it very much either.... of course... it's worlds better than the regular masking tape, but it's no match for the blue one from 3M.

PS: The 3M blue tape I guess it's the Scotch Blue...

Thanks for the input guys.

What kind if tape did you use? I assume the kind of tape you used here is irrelevant and just a matter of evening out the painted surface

I'd assume that a lot of us have experienced this. I'm actually surprised that we don't see more threads like this. I learned early on to stay away from the tape's edge when doing 50/50 panels for photos. The one time I experienced this was the last time. I had to break out a wool pad to remove the line.

Agreed.... I thought it was just me before this thread.... Anyway I've the least trouble with the scotch blue.
the regular masking tape wont ever touch a paint again if it depends on me.

I was using 3m blue masking tape. I ended up just giving up and throwing a coat of wax on it, Room mate didn't notice until I pointed it out, and didnt really care.
