Wow what a great response thank you everyone.
Thanks Tread what you did with your fender was great and a perfect fix for the trouble i was having but the credit is all yours my friend
Hi Hermesminiatures the pigments used on the tracks were Bragdon's "dust bowl brown" and "weathered barn".
Hi Eric i did replace the grills with some scratch built ones using plastic sheet and some scrap PE, they are not perfect but as you say better than the kit ones which in my opinion are the weakest point in these great kits.
Hi Manny, the weathering was done with about 97% oil washes (around 20 or so) and at the end a dry application of pigments in select places to blend it all together.
Stevo my man as always i appreciate your comments the track sufaces do actually show bare steel but the pics do not reflect this look at where the track is under the fenders or one of the pics which is blurred show it better also, i think the lights tend to block it.
Hi Ben the only point i apply pigments is at the very end the last thing, i apply them dry by dipping my brush into them then scrubb them into the corners and places i want them i then scrubb and wipe/blow away the loose pigments the flat finished will hold the pigments perfectly, i rarely apply them any other way i use oil washes for all the other weathering, almost all the weathering you see is oil washes the pigments merely tie them together and give a dusty finished look to it.
Matt, Ps1scw, Doog, Dale, Bill, Crockett, Larry, Grant and M1garand I again thank you all for the the great comments you are all very kind.
