Hey guys, I'm not sure where to post this question, but here goes. I borrowed a 3D scanner today, in the hopes of scanning our engine (and some of it's parts separately), so that we can do a 3D model of it, and use it to lay out our tuned intake and exhaust systems inside the cowl, and also design it around our engine mount and other stuff in there. We started a scan today, but the aluminum parts are too reflective to get a usable scan. Ideally, the parts need to be matt white or gray. Thus, we need to find some sort of sprayable material that - once we're done scanning - we can easily wash off somehow, without adversely affecting our parts. Does anyone know of such a material/product? I was thinking of something like Gouache? Need something - almost like PVA - that can rinse off. Any ideas? Thanks.
