I did a small boat that had through bolts. Fortunately the interior was rolled gelcoat. After filling and smoothing I rolled gelcoat to match. Looked good.
I have filled a few holes in Touché's headliner. I beveled them with a cone shaped grinding stone in a drill then filled them with gelpaste from Spectrum Color. Unfortunately matching the color of your interior might be difficult. I'd sure give it a shot with white gelpaste tinted with a tiny amount of black, yellow and brown. There are gelpaste kits out there. Dennis C.
