NHA:
MOST automotive garages DO NOT offer rust repair or bodywork. they don't have the facilities to offer such services. ie: spray booth, paint/chemical explosion-proof cabinets, or an entire garage bay devoted to rust repair, or bodywork.
that's why there are so many 'body shops'. they, in turn, don't do mechanical repairs...
fraud,regarding failed mechanical parts,is most likely a common occurence, but failure for rust? not so much.
(i used to work in a garage years ago, & performed inspections)
The whole point is that it's a scam/fraud...
And any garage with a lift can take care of "rust" on the underside/unibody/chassis of a vehicle...
Point being...the garage does NOT need any special equipment besides the equipment they already have(lift, grinder, wire wheel, can of undercoating)...
And if the customer is a regular with no "working knowledge" of the inspection criteria...or what chassis/unibody/underbody "rust" IS and is NOT structural...and/or passable...then they should be totally comfortable with the honesty of their service establishment...
As always...buyer beware...
I've seen more scams/fraud...scams/fraud on anything and everything...than I can even recount...
Example: "Spelling your name in all capital letters is different than all lower case and/or spelled normally"...scam/fraud...(do people still fall for this?)
Re: The above example...clarification...IMHO...almost all "law" is a scam/fraud...like 99.999 percent...
IMHO...THE ONE LAW: The Non-Aggression Principle (i.e. Don't start it...but make sure you repel/destroy those who commit aggression/force/fraud)
IMHO...Factual Reality: Each and every human being living in the past/present/future could/can/will be put in one of two categories...
Category One: All the human beings who observe the non-aggression principle and "just want to be left alone"...
Category Two: All the human beings who "advocate/condone/endorse/employ/participate-in" aggression/force/fraud either "directly" and/or "indirectly"...MORE COMMONLY KNOWN AS "TAKERS"...WHO SHOULD ALWAYS BE REPELLED AND DESTROYED...
