I’ve got some Dyane tinware for the Burton engine, this has the “back end of a horse power” forced induction take off and the cylinder covers are metal rather than whatever it is the later 2CVs used. However, it’s seen better days so needs some renovation.
First off the engine mounts needed removing with the aid of heat, Super Crack Ultra, and an impact driver. With that done I’ve declarted them using pound shop oven cleaner.
Next step will be to give them a thorough going over with various grades of abrasive.
