I use a L*** baseplate in almost ever one of my posts and I don't have an issueSome parts you'd still be able to tell, such as baseplates. No matter what you do to a L*** baseplate, it's still recognisable.If you could sand the logos off you would be good. But you would have to find matching colors to cover up the stress marks or you could take your idea and paint them black or gray.
Dude! That's an awesome idea, I'd just need to paint 'em black or grey.
I guess just experiment, and tell us what works.
