C'mon ppl...jeez....the best way to "weather" is to completely cover the lid in silver paint,not chrome,then latex it with a brush on the parts you want to see as metal,or any rubber liquid will do...i use the same latex i use for molding........then go for it with your rustoleum and krylon spray cans.The last paint(before clear-coat,if your'e going that way)is a flat black,2 coats,one short-shot spray on the "carbon scoring" areas,like the cheeks,etc.then a long spray 2' away for the "dusting " effect.............and FORGET Ebony rub'n'buff.it's a wax.......you can't paint,or clear-coat over it..........I'm on my 63rd lid.........I sell the to costume hire stores....and I know what works,out in the field,as it were..........btw.mustard contains acidic properties..........no pro propmaker uses it.ever........I know...I am one.
