Actually, chieffy's former gas station on P. Gil still does 3M undercoats. Nelson, the guy who would do it for chieffy, is still there. He's still the one who does the undercoating. For the same price. Problem is, the new owner of the gas station does not provide a budget for old newspapers (a kilo's worth) and masking tape. So, Nelson requests the customer to bring his own papers and masking tape.;) I would suppose that since it's the same guy who does the job, the quality would still be more or less the same.
BTW, Nelson tells me the chieffy Ronald still drops by once in a while to get his oil changed there.
