Thanks Kieran and Nelson,much appreciated. Kieran,I found the build not to bad,I took my time with them (3 in total)and really just sanded them on the underside until they sat flush on the chassis.Again,just sanding the various parts to ensure they were all flush (or flush-ish) was worth the effort to make sure the body sat well on the chassis.I actually completed the build over the Christmas holidays,they have been in limbo awaiting painting as I did not know what paint to use.Last week in B & Q, I stumbled across a small tin of duck egg blue gloss,and although I only ever paint my stock matt,it looked ok,so I got it and with the bit of weathering I think they have turned out ok.
