Jacking Pucks
Even if the body panels don't get broken or cracked, if the lift is contacting them, it has to be at least scratching them. I know one thing for certain, it can't be doing them any good.
If they refuse they loose my business.

I usually take my wheels to them anyway. Nobody jacks up my car but me.
Knock on wood.
Don't waste your money on expensive pucks.

Save your money going the hockey puck route and do another mod.

I went to Discount Tire, once upon a time, and one of the mechanics "allegedly" scratched my car and broke an antenna off the car. I say "allegedly" because the manager told me that I had to prove that the mechanic broke it
Now, if I have tire probs I go to a specialty Corvette shop where they use and provide jacking pucks all the way around the car.
Bought mine from Fleabay also. Used all four one time when getting tires, and two of 'em another time when working on brakes.Tim Glover

They aren't the cheapest way to go (~$150), but IMHO the best. The pads are always there and you've killed two birds with one stone.

In contrast to lots of other things the cost for that is not much.....my opinion.
Be carefull leaving the pucks in all the time.

A buddy of mine lost a puck and damaged the hole that they go in by scraping a speed bump.

Just a fyi






Don't believe what some tire jockey tells you. Here are the GM instructions from the Service Manual:
Lifting and Jacking the Vehicle
Caution
To help avoid personal injury, always use jack stands when you are working on or under any vehicle that is supported only by a jack.
Caution
To avoid any vehicle damage, serious personal injury or death when major components are removed from the vehicle and the vehicle is supported by a hoist, support the vehicle with jack stands at the opposite end from which the components are being removed.
Notice
When you are jacking or lifting a vehicle at the frame side rails or other prescribed lift points, be certain that the lift pads do not contact the catalytic converter, the brake pipes or the fuel lines. If such contact occurs, vehicle damage or unsatisfactory vehicle performance may result.
Before you begin any lifting procedure, be sure the vehicle is on a clean, hard, level surface. Be sure all the lifting equipment meets weight standards and is in good working order. Be sure all the vehicle loads are equally distributed and secure. If you are only supporting the vehicle at the frame side rails, make sure the lifting equipment does not put too much stress on or weaken the frame side rails.
If you use any other lifting methods than those called out, take special care not to damage the fuel tanks, the exhaust system or the underbody.
Notice
When you are jacking the vehicle at the front locations, be certain that the jack or the jack lift pad does not contact the front fascia, front fascia air dam, or the front fenders. If such contact occurs, vehicle damage may result. When jacking at selected front locations additional clearance may be required for the jacking points.
