I want to make my current 2 pup Cab a Single pup relic. (Especial) . It's a Squier, so I'm not worried about screwing it up (too bad). I have already stripped the old paint off to wood. Is there any way at all to fill the neck pup cavity without it showing through over time? It will be a solid black relic finish. I know this has been asked a hundred times, just wanting to know if anyone has done something other than bondo that won't look crazy ugly in six months.
