I made a dish myself based on all what I read here. I made it out of wooden parabola ribs, laid it up with 4mm plywood, then fibreglassed it.Then, to make it reflective, based on what I read here, I used the cold galvanizing spray cans (with zinc added) from Ace Hardware. I made a 1.4m dish, 14cm deep, focal point 87.5cm. Today I was finally done, but did not get any results... I would like someone to verify if this spray actually works as a reflector. I am contemplating to stick aluminum foil over it.  Also, I have a universal lnbf, the distance (focal point) is 87.5cm from center of dish, the question is, is that from the center of dish to the white plastic cover of the lnbf or slightly more inwards (feedhorn)?I will upload pictures later if y'all are interested. Thanks.</blockquote>
