ok the dilema is over I ended up trying to strip the satin off by having it sit in a tub of 90% rubbing alcohol just deep enough to get the black off. it did not strip off but it dulled it, so then I repainted it with a flat craft paint, not as smooth but acceptable so the shell of the engine is painted, next is painting the handrails and stanchions black presently they are white ( this was a BN sd40-2 green and black it is now black and gray for MRail)
