This small selection of tools...
This small selection of tools are what George uses for about 90 percent of his straightening. The black blob at the top of the group is a rubber-like substance used to back up the trim while it's being hammered on. It's from the medical field, but is very similar to artist's erasers (found at art supply stores), or Silly Putty. Modeling clay would also work.

They say the Devil's in the details, and no detail makes as big a statement on your car as stainless steel trim. Stainless trim can make or break a car on the show field-even if the car's paint is perfect, the engine bay is detailed and the interior is spotless, dinged and dull stainless will always catch your eye, ensuring that becomes the focal point. Conversely, mirror-perfect trim will make up for other areas of your car that may be lacking. We don't know why it seems that way, but that's the funny thing about details.
Straightening and polishing trim is an art that takes a lot of practice to master (and more than a few ruined pieces). We met George Iverson, of Iverson Automotive, while shopping for someone to handle the trim on the Holley Project Road Runner. John Balow of Muscle Car Restorations, the shop handling the project, sends all his trim to Iverson. George got started in the buffing business several years ago, when he did the trim on one of his project cars. His stainless results were very good, and he started getting some "on the side" business from his buddies' cars, then from their friends, and their friends' friends. Eventually, his word-of-mouth reputation forced him to make "The Decision"-back off of doing what he really enjoyed, or ditch his regular (and very well-paying) job to make a go at it. "My only regret is that I didn't start doing this full time 10 years earlier!" George told us.
Along the way to George's reputation, he's learned the ins and outs of polishing different metals, from stainless and aluminum to custom bronze sculpture done by local artists. In addition to a 10-step trim polishing process he's developed over the years, he's also formulated and patented a unique "finishing" buffing compound called "Iverson's Secret Sauce" that he credits with putting his finished trim "over the top."
"There's often a faint white or milky residue left on a piece after the polishing process," George said. "I spent years formulating a compound that would eliminate that final haze." We don't know what's in it, but when he's done with a piece of trim, it literally looks like a mirror. George has also developed a rather time-consuming process to repair and restore pot metal to like-new condition. He showed us a pair of Chrysler 300G taillight assemblies that were incredible.
There are pitfalls to polishing your own stainless trim, the first being the proper equipment, and we're not talking strictly hand tools or buffing wheels. For example, the polishing process generates an extreme amount or heat, necessitating thick welder's gloves to protect the hands. George goes through two pairs of gloves a week, at $25 per pair. The cheaper gloves don't last even that long, and in the long run the more expensive gloves are the most cost effective. His double-layered Carhart canvas jeans last about two weeks. George does more polishing in two weeks than most of us will do in our lives, but you can plan on going through the same bill of materials just doing the trim from one car.
The intense heat generated during the buffing process also has two other ramifications. The first is obvious-heat will warp the metal. Long, thin, flat panels such as rocker moldings will warp and distort if they're heated too high for too long. The other difficulty is that stainless steel trim isn't actually pure stainless, it's an alloy, as auto manufacturers usually added iron to the stainless. Stainless and iron have two different melting points, and if the trim is heated past a certain point, the iron can actually melt out of the trim piece, creating what appears to be orange peel on the surface of the stainless. This is even more of a problem with aluminum trim, where too much pressure and rpm will cause black streaks, or "mouse tails," which will have to be sanded out. George has separate buffing motors for stainless and aluminum, with the motors spinning at 3200 rpm for stainless, while the wheels he uses for aluminum are spun at about 1800 rpm.
This is a compound dent on...
This is a compound dent on a curved piece of trim. There are a lot of things going on with this dent; the crown is flattened going around the curve, the main character ridge is also flattened, the area where George is pointing has also been pushed up, much like the ridge around a crater.
The first thing to do is clean...
The first thing to do is clean the work area. George uses an air tool to clean the front and back sides of the piece, followed up with a Scotch Brite pad to get any areas the wheel couldn't reach.
This piece was dented underneath...
This piece was dented underneath the lip, so the lip had to be opened up. George uses a small side dikes to uncurl it.
Nothing fancy here, just start...
Nothing fancy here, just start pounding out the dent. One thing George stresses is to work the area smooth with the tools, rather than push it past the original contours and then file off any high spots. This creates thin spots in the metal, which will heat quicker during the buffing process, easily ruining your piece.
George uses a flat chisel...
George uses a flat chisel to re-establish the ridge in the piece. The edge of the chisel has been blunted so it doesn't cut the piece.
George didn't employ the putty...
George didn't employ the putty while straightening this piece, but here he's showing how it conforms to the part and fits tight into the back of it. Any high spots on the front from his repair would be tapped down, using the putty to back up the blows. He then refolds the lip after the dents have been straightened out.
