If this really works there would be no need to wash our bikes ever again

Well at least you got a reply, I have got feck all so far.
I reckon it would mess up the plastic as others have mentioned, so polish and elbow grease continues :crazy:

what’s the opinion on using this to stop the damp getting into my 50 year old brickwork?

Surely there are cheaper products already on the market for that? PVA?
