Well... Yes and no. It takes a Herculean effort to make a vac look like an injection molded one.
The irony is that today, despite the decline in vac popularity, there has never been more aftermarket parts to choose from. Heck, even complete resin airliner jet pod assemblies can be had. Gone are the days scrounging around old kits to hopefully find a matching set of wheels or radial engines and propellers.
I only pushed two vacs across the finish line, a War of the Worlds Martian war machine and a scratchbuilt Berezniak-Isaev BI-1. The martian war machine's Metalizer copper finish has since oxidized to look like a dirty penny.
If I could get another chance with a vac kit I once owned, it would be Nova's 1/72 C-141 Starlifter.
