I got a Sig Kougar the other day, flew it with a Webra 50 on it, it flies great, a little fast

and a little small for me. It is currently on some unknow covering, maybe coverall and painted red, the whole plane, I really want some type of contrast on the wing to make it a bit easier to see. Would ultra cote stick and or cover? or would I be better painting it?
I was thinking of some white stripes under the wing, any other ideas?
Thanks
Jon
