The best tape is the 3M 483, but the price has gotten so out of hand that it is hard to justify. It will not sink in as much as the other tapes. One option is to make some thin mylar covers that you tape over with the softer tape. This will prevent the tape from sinking into the gap.

I still have a few rolls of 483 that use only when I can’t use something else. I have been researching alternatives and looking to buy some to test.

3M white electrical tape is what I use for anything that doesn’t need 483.

Why is this the best?????

My question is, With Wing and tail tape on why do I get a very loud howling when I Fly faster than 90 knots. And get no howling if I don’t tape the wings and tail.?
LAK17a/18.
I don’t mean to hijack this thread.

90% of the time this is a loose tape edge on lower wing root, 6 - 12" in front of trailing edge. Inspect with pocket knife or similar after flight. It may still look sealed.

Gaffers tape is a polyurethane over a cloth laminate and may not stretch the way you require.
Also much thicker.
Gaffer tape is designed specifically not to leave glue residue behind when removed (specifically useful eg. in the film industry, where tape has to be applied to carpets, clothing, sets etc.). It's basically less-sticky duct tape. I wouldn't use it on a glider, unless you have a phobia about glue residue.

I put mine on two seasons ago and it hasn't come off yet. I guess it has something to do with good surface preparation as well.
