I just got my MX2 and am in the process of upgrading the u/c mounting, being an aircraft structures tech I have a wide choice of aircraft grade ally to choose from, if I can work out how to post pics I will try to do so. Decals, P.I.T.A. fitting them, took ages then sealed all edges with polyurethane clear varnish, it looks like it worked OK but time will tell, had no adverse effect on the foam.
