When I got the stand, (which are already blurry as in the picures ), I tried to wash the blur out using water. Being unsuccessful on my first attempt, I tried using the green sponge , the one used to scratch tough stains, and guess what...the base become even more blurry than ever!. Luckily I didnt scratch all the other parts as well....
I also realized that the blur are somekind of an oxidation on the surfaces of the arcylics which can be removed by abrading the surfaces with cloth, which I tried on the rods and the small round plate. now, my rods and plate are sitting in the box, waiting for the base to be masked with clear coating tomorrow morning....wish me luck!...
