Re: 3M Tape DAMAGED window molding!
At this point i would tape the areas that weren't taped before to at least give everything a uniform appearance. Looks like the tape pulled up the embedded dirt and grime from the trim leaving that shiny look.

Re: 3M Tape DAMAGED window molding!
How long did you have the tape on the trim and was it ever in the sun?

Re: 3M Tape DAMAGED window molding!
I think its more the tape removed something on the trim, rather than damaged it. I would probably try a good APC, clean the trim, then apply a nice trim sealant or coating to restore it.

I have tried to clean it, scrape it, and rub it... no luck removing it.

I did try this briefly and the tape did not leave the same texture or shine... perhaps it needs to sit longer. The original tape was on the car for a few days.

Car was only in the sun a couple of minutes, tape was on car a total of a few days.

Re: 3M Tape DAMAGED window molding!
Looks like the adhesive in the tape had a chemical reaction with the trim. I never leave tape on the trim overnight for this reason and I find some tapes are more susceptible to doing this than others. That car is also pretty old so that could be a factor as well.
FYI: Most masking tapes have a "clean release" time rating on them.

After much research I decided to take the extra step and mask off vulnerable areas of the car before compounding such as window moldings, grill, side skirts, front lip, antenna, keyholes etc.
Removing the 3M automotive masking tape has revealed seriously upsetting results. The tape has left shiny texture marks on the rubber and plastic window trim.
1) Windshield molding that runs the length of A pillar, up along roof line as rain gutter, and down rear window C pillar.
2) Same trim
3) Molding around side window
4) Outside shots
5) Notice the windshield molding runs from windshield up along roof line to bottom of rear window
6) The culprit...
This is very upsetting. Any next step advice is welcomed. The texture and shine does not come off the trim, it seems to be imbedded into the molding
I've been selling packaging and masking items from 3M and other manufacturers for 25 years.
So here's my questions:
How long was the tape on the vehicle?
Was it inside during the taping and correction process?
Since the vehicle is dark colored I ask that question to see if it was exposed to heat or excessive uv rays?
The usual issue with cheaper masking and packaging tapes is adhesive transfer, ie the tape leaving adhesive residue and not releasing cleanly form the surface.
I've read your responses so no need to reply to this post. I wouldn't leave tape on for the amount of time you did. On the 3m spec sheet for that product it would likley state how long it can be left on and what it's operating temperatures are. You could google that and it should take you to 3m's website and spec sheet.

Re: 3M Tape DAMAGED window molding!
This is from 3M's website assuming what you have is the #233 tape.
This unique, green colored tape has excellent conform-ability, Transfer resistance, and is resistant to bleed through. 233+ is also has better UV resistance than traditional masking tapes. Adhesion to steel: 38oz./in.width. Tensile: 25lbs/in. Tape thickness: 6.7 mils. Temp range: 250F(121C) for 30 minutes
The temp range refers to if it were in a paint booth. I'm kind of surprised they don't make any reference to dwell time.

The OP is using the cheaper 3M stuff but the 233+ should have a release time of 3 days.
