Yes dear, browse thru this post . . Practice Weathering Part II . . . this is weathering we all aspire to I’m sure, Dave @Kraftstoff3 used Rusto on his works if I remember correctly and they look flippin’ awesome, why my application didn’t work I dunno but one has to be sure to use the exact same product to get the exact same results, I may have failed in that respect 
BTW Joe, what are you using to get a flat finish? I’ve tried Model Master, Floquil, AK Real and now Rustoleum, if you tell me you’re useing RightGuard antipersperant and show a picture where it worked I’d consider it.
