I've been considering waxoyling the underside (extended chassis/brake pipes, etc) of our Hymer. From old, I'd always considered 'Finnegans' Waxoyl to be the premium product..but I can't find it anywhere. Lots of mention of 'Hammerite Waxoyl' though. So, does Finnegans no longer exist? Have Hammerite bought the patent rights? Is it the same thing?? Or, is there a better new -fangled product these days (Dinitrol)? Thanks Confused.com!
