Thank you Ron, JD and Tamer.
I got a little sidetracked this weekend! I recently acquired a G.I Joes 1986 Cobra Stun, the vehicle is in good condition but in need of clean. The hatches had been supplied but they had been broken into pieces and it had one wheel trim. It is missing two trims, both flags and the rear swivel gun. After looking through sites eBay and forums on Facebook, I decided to cast some of the parts I needed, help improve my casting skills.
To start, boiled water was used to wash the entire vehicle. I using the parts of the hatches which had been supplied, I was able to piece together a whole one. I made up a couple of moulds using Blu-Stuff, the first mould of the repaired hatch, the second mould of the remaining wheel trim.
