50 years ago, I learned to ASSUME = makes an ASS out of U and ME! It is frustrating and embarrassing to admit I do not always follow the lesson (which should have been) learned. Maybe when I grow up I’ll get better. I assumed using a blue painters tape would produce an even better result than my tried-and-true previous process but it came back to bite me in the butt.
Lynn, thank you for the kind words. While I was 95% certain the blue tape was the offender, Larry Pollock’s post was the deciding factor which drove the nail in the coffin; he needs to be commended as well.
James, while you offer a valid point to consider concerning contamination sources, I am now confident the source in this case is the formula 3M uses with their new blue tape.
Phil, thank you as well. Using a contaminated tape to even “tack threads to the blank for trims” will get on the builder’s fingers and may (probably will) eventually contaminate the wrap. I think this aspect may have added to Larry’s scenario.
Allow me to clarify and verify that the decals from MudHole or Decal Connection, as well as the CTS Crystal Coat thread finish was NOT the source of the contamination problems described above. They are all great products.
So, there you have it. Contamination can come from even the least expected source. Assuming you have it all under control (such as I did) can come back to bite you in the buttocks.

Sounds like the problem has been identified with the particular tape using a different adhesive than it used in the past.

Good information.

i have learned that by using CP i don,t have to be concerned about where contamination comes from..it,s been cancelled out of the equation..the same with bubbles in wraps.

Well Mark and Larry, you saved me. About 2 weeks ago I found a roll of 3M painter tape my son got to do trim work on his truck and put it in with my rodbuilding stuff. Just looked at it and sure enough 2093. Luckily, (I hope) I laid it inside my regular roll of masking tape but not contacting it on a sheet of paper. I'm hoping this contamination does not spread too easily. If it' s on the tape adhesive it's also on the blue back side of the tape. I may have marked a reelseat location on a new blank with this tape, not sure, what should I use to clean the blank prior to building just in case? If I clean blanks at all prior to building I usually use U-40 brush cleaner.

If using it to simply mark a reel seat location I don't think anything more than the usual ScotchBrite treatment to get good epoxy bonding is required. U40 brush cleaner has to be a pretty complex mix of chemicals, some of which are designed to break down epoxy, so I wouldn't use it on a blank to clean it.

U-40 brush cleaner is recommended to be used for cleaning blanks prior to building. It's in the product description on the web site with the epoxies.

Lynn, if I only save one person from the aggravation I encountered, then it was worth the effort! I have not used U40 Brush Cleaner but if Ralph O’Quinn formulated it, it must be good. I have always used acetone with anything related to composites, obviously epoxy included. Tom may disagree, and I totally understand his position if not even agree, but the acetone wipe-down prior to applying the third attempt to coat my logo is what saved me and the build.

Thanks, Lynn. Didn't know that, do now.

Lynn and Michael, without having the product description/ directions of U40 Brush Cleaner as Lynn suggested reading, I have adopted Tom, Roger, possibly Ralph O”Quinn and others recommendation, if not insistence, of scoffing the surface after the application of any solvent, be it U40, acetone, DNA and such; it simply makes good, practical sense. Obviously, I could not scoff the decal in my scenario and, so, applied the finish right after the wipe-down (including a degas period) with acetone. Thankfully, it worked.

Thanks Mark, I have acetone also. Whatever cures it I'm all for it.
