I had peeling problems with thick tape (3M Diamond Grade) because it has enough inherent stiffness that it tries to straighten out. I was eyeballing some Nikkalite Crystal Grade for this project because it also has high reflection specs, but then I Googled to find out if it was thick & stiff, and found it was described as being thick like a credit-card. Great for making street signs, I'm sure, but not for sticking to sharply-curved surfaces.

So I went with some more Reflexite V82 here, which is the premium 10-year grade (V92 is the 5-year grade, not as reflective but still very good prismatic tape). I've been using this stuff on my road-commuting bike for a while without peeling or any noticable dirt-attraction problem, so it seems to be a good pick.

The Reflexite V82 I put on the frame last night is from night-gear.com. The DOT Conspicuity version is 2 inches wide, and the blue stuff is the 1-inch wide. It's thin enough that it doesn't try to peel itself off. Tip: don't try to put any stretching force on it when sticking it to the frame, just lay it on. It's infuriatingly sticky

The tape across the rear of the fenders in little strips, and up the rear of the seatstays, is Peterson Manufacturing DOT Conspicuity tape. It's a good prismatic tape you can find at Fred Meyer and auto-parts stores in a package like this:



Identi-tape.com carries the Reflexite Daybright V92 in lots of colors, that's another good pick if you don't mind the triangle pattern.

The tape along the forward arch of the rear fender, and near the fork on the edges of the front fender, is 3M Scotchlite glass-bead tape. It's vinyl and has juuuust enough 3-dimensional flexibility that I was able to arch it along the edges of the fenders (prismatic stuff doesn't stretch like that).

The rims are a mix of the silver 3M Scotchlite glass-bead tape and the Reflexite V82, but I think I'm going to just lay Reflexite over the Scotchlite because it's sooooo much more reflective and I have plenty left
