FWIW, my (purchased) '91 RV-4 has had the original stainless tape on the flap faying surfaces since new. Invisible with the flaps up, and a nice flap angle indicator as they're extended (if you bother to look). :-)

Felt tape is a good idea. Recently painted my RV4 and used the 3M paint protective film from Flyboys and Teflon tape under wing skin. Looks and performs great, hardly noticeable. My flap to wing is a tight interface and this combination works well to help reduce friction. As mentioned, use masking tape as guideline for a nice straight edge, float it on wet and work out the air bubbles.

Thanks for the replies. Does anyone have experience with using Velcro loop on the underside and the flyboys 3m tape on the flap? Leaning that direction.

Default Felt Tape

I am about to get my RV-10 painted. Do you think the felt tape would be good on the 10 also? Ron, what do you think? Is yours still holding up?

Lasts a lot longer than that clear tape.

Depending on the wing/flap fit some are very tight and others not so much. The UHMW tape is very slick and allows for the flap to smoothly extend/retract if you have tight fitting flaps, other products that create friction may cause issues. I can't imagine adding something that is 1/16" thick in this area unless your flaps don't fit snugly. Also don't forget that air pressure isn't going to improve the situation. Some folks that have installed the paint protection tape have trouble with binding.

I wouldn't recommend it. Felt is the perfect material to collect dirt. Once the dirt is collected and embedded in the felt material, you have created a piece of fine grit sandpaper. Other than the 10 or 14, this would be impossible to clean without removing the flap control arms.

Suggest either the 3M tape on the flap or a tape like UHMW or Teflon on the underside of the skin. The can collect dirt, but substantially less than felt.

The -10 and -14 use slotted flaps. I wouldn’t use anything that materially changed the geometry of the slot.

Default teflon tape

I ended up putting just a 1/2 inch piece of teflon tape under the trailing edge of the wing so if the flap hits it it slides on that. Two years flying, no issues.

Pick paint protection film over UHMW any day of the week.
