Uhhhh...why do you think that the foil will make some sort of inpenetratable layer? It will do the EXACT same thing as the wrap. The rapid change of driving it as a daily driver will make the same stuff rot in the same place.
Soon to have some MHS parts, cams, 'luminum block, lower compression, ported heads, autorotor, and need to make long tubes. I have almost all the stuff and need some #42-50s a bypass valve, and maybe a few other things.
