Can anyone reccommend a suitable material for covering the glare shield inside the canopy? I am tempted to either paint it flat black or epoxiing some vinyl or suede material to it. Any suggestions? Also what is the purpose of the dacron tape as used in conjunction with the West Sys. products? And can I use a mixture of Phosphoric acid and water to etch my aluminum surfaces? In a 5 to one ratio? Tia. Jim.
