We bought this stupid thing off ebay that keeps insects out your windows, but it required to be stuck around the inner frame, it was velcro strips and you put fabric mesh over it to keep insects out, anyways, it was rubbish so we ended up taking it down, but in order to keep it up, it kept falling down u see, I had the brainwave of using superglue, then the velcro strips wouldnt come off so had to be yanked down, but its taken some of the velcro strip backing with it and left it on the window and I cant for the life of me get it off, is it possible to paint over it? the bits left behind are only small but very noticable, I got most of it off, but it needs painting over, I bought a PVC primer, but its not thick enough, is there anything else I can get to paint over it? the place I bought the PVC primer said u can use ordinary external white gloss, but I dont want them really shiny lol, I just want to make it look normal, any ideas?
