Anyhow, IMO Con-Tact is fine, but get a small roll of clear Con-Tact as well
to put over the top of any tactile surfaces as an overlay. That way you wear
out the clear layer instead! This is a much cheaper option than going with
plexi or lexan, both of which are also not that easy to cut. Also, if the
cleat layer becomes badly scuffed or scratched you can heat it a little with
a hair dryer to soften the adhesive, then remove it and put on a new clear
layer.
Another option is that if you are reasonable at tinkering with graphic apps
and have a decent colour printer, you can print up your own custom
graphics - Kelsey at
www.oscar.com has some nice 'compass' style pics that
you place where the joysticks will go so they act as directionals. You can
obviously add your own colours, patterns etc to achieve the look you want
for your panel. This can result in a pretty stunning control panel!! Just
make sure you use TWO layers of clear Con-Tact if you go this way, so you
can remove and replace the top layer as mentioned above.
