I painted mine in silver, left a day to dry then went over with a satin black spray, leave to dry for another day the I used steel wool on the edges and areas that would be worn, ie: where the hands would hold, putting into holster, as if it had been knocked or chipped being dropped or placed down. Once I was happy with the weathering I used a satin clear to lock the weathering so it will not change, If I didn't eventually the siver would wear off and you would see the white pvc. BTW it was mentioned to me not to weather the hand grip as the original ones were plastic so wouldn't weather, just paint gloss black. Have a look at my build theads for my results, links in my signature, bit hard to see clearly but will give you an idea. Good luck with yours
