Well first I need to know where I can get acrylic plexiglass in Karachi as I want to install a side window on my current case. I also wan't to paint my casing but I'm confused on how to do it. Do I have to sand paper off the original paint then spray paint it over with the desired color or can I use brush paints, for example acrylic paints. Also how do I get the glossiness effect after i finish painting it? My case is originally black and I want do a black (original), white, and blue color combination with a tron legacy type decal, so do I have to first sand paper the area I'm going to be applying blue and white over or can I just apply the paints over my stock black color? Also is there any shop/person in Karachi that does case modifications?
