Making a Glider Easier to See in the Air

I live in a fairly busy area, airplane wise. Just last weekend I
spotted a single engine plane coming more or less straight at me at my
altitude. I quickly banked to 1) get out of the way and 2) be more
visible to the approaching airplane. I didn't notice any reaction so I
don't know if he saw me or not.

Face it, airplanes are difficult to see in the best of times and a
glider is generally white which makes it more problematic. I have
been told that is why European gliders have red wing tips.

This brings up a possible idea. No, not anti-collision lights. How
about reflective tape. Radio Control glider pilots use a hologram like
tape called Sky Sheen to help them spot their ships from the ground. I
was at a RC glider field last summer and saw it in action. I found a
source (but no picture) at;

The question is, might this work for us? Is there a worry about
damaging the wing surface? Spoiling the aerodynamics? Others?
