e-Roottoot, as you mentioned being an (Ex) In the auto trade, where do you stand personally, on the battery terminal PJ issue? I have known of applying either that or proper branded terminal protecting substances, ever since starting off on my driving career, back in the late 70's but when I purchased the Skud, The instructions/service schedule says "NO"!

That said, a good, clean, well charged and firmly connected battery perhaps does not need the attention.
