Hi all. I've been rebuilding the start city event kick out hole on my Roadshow. The stainless scoop needs welding and while its out I've decided to sort the hole out. I've bought a hole protector (upper and lower) but the wood needs slight filling before I fit the top protector as the edges are a little worn away and it will just get dented like the old one if I leave a gap beneath it. Question is, what filler does everyone use in these cases? Regular car body filler, wood filler chemical metal etc? Many thanks!
