I got a Big problem with my airport, so... heres the thing... I usually print my foils in normal office paper and glue them with stick glue, wich is a "dry" kind of glue and doesnt blur the foil... but after like 1 month (without sun light, of course) the foil is all green... so I have to change the foil, Should I change the paper? or the glue?
Does anybody else has this problem???

Thanks,
Armando
