Body seams leak into trunk - suggestions?
 

My '68 GTO has a slight leak into the trunk - and my perfectly restored trunk now has some slight surface rust (no big deal but still...) and I think I've pinpointed the leak to a very small gap in the body filler seam.
Any suggestions to fill that gap?
Thanks...

You can use seam sealer from underneath if you can,then on top. Lightly sand around area first so that you can paint later after it dries.Good luck.
