Caveats!!
Some caveats may be in order here. I just finished my carb base and based on this most recent use of the tape, I can't heartily recommend it!
It's a new roll and maybe the formulation changed or the application is different enough, but it was a PITA to get off. And it left lots of glue residue. Go figure!
The previous uses were an aluminum intake manifold, an aluminum water pump and an aluminum alternator housing. In nearly every case, the tape was laid across a flat surface and trimmed around the edges. A varying amount of what the tape covered was open air space, ie the carb mating surface of the intake manifold, or the mating surfaces of the water pump. In these applications, the tape turned slightly brown but was able to be peeling off nearly intake - it was brittle. A quick wipe with lacquer thinner cleaned off any glue.
The most recent use was the base plate for a Holley carb. Again the mating surfaces were covered plus all the linkage on the side of the base. The tape did NOT remove easily from the mating surfaces, but it wasn't much of a problem since they were flat. The linkage was another story, as I said, major PITA. And left lots of glue!
I also bought some purple 30 day tape and used it on the bottom of the plate. It's glue was not very aggressive and altho did not fall off, it gave me some concern. The tape did remove better than the blue, but not like previous uses.
So there you have it. Proceed at your own risk. YMMV. Please report back on successes/failures so the rest of us may know.
