Yeah, just used body filler on the trades, sanded it flush with the rest of the slide, then sprayed. (after stripping and sanding the rest of the slide obviously). I'm a bit worried about the longevity of the finish, but I'm reluctant to give it a clearcoat in case it makes it shiny.
Hadn't thought of doing the recoil rod, I'll get that done tomorrow!
Cheers,
Graham
