Hertz, Hitches, Running Boards & Clear Coat: An Installer's OEM vs Aftermarket Guide

Let me clear something up first. If you typed "Hertz car rental Baton Rouge" or "rental hertz car," you're probably looking for a rental car, not car audio. I get it—search results overlap. In our shop, Hertz is the name on the audio and electronics we install. The trucks we work on are the same kinds of vehicles that end up in rental fleets: they need audio, sure, but they also need running boards, trailer hitches, and paint care before they're customer-ready.

A quick intro: I've been handling Hertz orders in a B2B shop for nine years. I've personally made and documented 14 significant mistakes—totaling roughly $18,000 in wasted budget. Now I run the checklist that keeps our installers from repeating my errors.

What This Comparison Is Really About

The biggest question I get from dealers and installers isn't "which brand is best." It's "should I quote the factory part or the aftermarket part?" This applies to all three of the jobs I'll cover: a TRD cast aluminum running board, a Ranger trailer hitch receiver, and the one everyone argues about—does car polish remove clear coat?

I'll compare factory and aftermarket on four things: fit, lead time, total cost, and real-world durability. At least one answer will surprise you.

TRD Cast Aluminum Running Board: Factory Board vs. Aftermarket

Last spring, a customer wanted a TRD cast aluminum running board for his Tacoma. He had the TRD sport package and wanted the accessory that looked like it belonged. The dealership could get it, but it would take a month. He asked if an aftermarket board was just as good.

Fit: Factory TRD boards are engineered around Toyota's body mount locations. In a perfect world, they bolt straight in. I've seen aftermarket "compatible" boards that needed bracket shimming or drilling. I drilled one once. It fit eventually, but the powder coat cracked six months later—and the customer remembered who drilled it. At least, that's been my experience with Toyota trucks.

Lead time: The factory part took four weeks—closer to four and a half, actually, when the dealership's system was behind. The aftermarket board arrived in two days. Not hard to guess which one made the customer happier that week.

Total cost: The factory board was about 60% more expensive. The aftermarket board came with good hardware and looked 90% the same. But "90% the same" is the catch. On a truck the customer plans to keep for a decade, that 10% might matter.

Durability surprise: I expected the aftermarket powder coat to fail first. It didn't. The factory board's finish also chipped after a customer dragged a metal toolbox across it. So don't tell yourself "OEM is indestructible"—it isn't.

Verdict: If the customer wants a perfect factory match and can wait, order the TRD cast aluminum running board. If they want function at a reasonable price, a good aftermarket board is a legitimate choice. Just measure the brackets before you drill anything.

Ranger Trailer Hitch Receiver: Factory vs. Aftermarket

A customer brought in a 2019 Ranger that didn't have the tow package. He bought a small camper and needed a hitch. The two quotes were: a factory Ranger trailer hitch receiver with harness, and an aftermarket Class III receiver from a parts supplier.

The mistake I keep seeing: They think the hitch is the rating. It isn't. A receiver is only part of the tow package. If the truck doesn't have the transmission cooler or trailer brake controller, a Class IV hitch won't make it safer to tow near maximum. I once recommended a cheaper aftermarket receiver to a customer without verifying the rest of the setup. He towed too much, overheated, and blamed me. The receiver was fine. The truck wasn't equipped.

Fit: On most Rangers, the factory receiver bolts into existing frame holes. Aftermarket hitches also use frame holes, but sometimes you'll need to trim the lower valance. Not a huge deal, but it's a step that adds risk and labor time.

Weld quality surprise: I wanted to believe the factory unit was perfect. But the aftermarket receiver I unboxed last year had cleaner, more consistent welds than the factory one sitting next to it. Never expected that. It was a reminder not to pick sides before looking at the actual parts.

Verdict: If the truck already has a tow package and the receiver is damaged, go factory for a straight swap. If you're retrofitting a Ranger that never had towing, a properly rated aftermarket Ranger trailer hitch receiver is often the better value—but check the truck's total tow package before you promise anything.

Does Car Polish Remove Clear Coat? The Answer Isn't No

This is the question I hear from shop owners, detailers, and worried truck owners: does car polish remove clear coat? Yes. It's supposed to. Polish works by removing a tiny layer of clear coat to level the surface and remove defects. The key is the word "tiny."

Most modern paint systems have clear coat about 1.5 to 2.0 mils thick—or 38 to 51 microns. A light finishing polish might remove 0.05 to 0.1 mil. A heavy cut compound on an aggressive pad can remove 0.3 mil or more in a few passes. Do that every few weeks, and you'll eventually hit color. That's not an opinion. That's arithmetic.

Reference: Clear coat thickness estimates are consistent with PPG and Sherwin-Williams refinish guidelines. I don't have hard data on how many hobbyists burn through paint, but based on my shop's repair work, most clear coat failures come from either too-aggressive polishing or not measuring before you start.

The reason I'm careful: In my first year, I made the classic mistake: I got a customer's car looking great under the lights, then "one more pass" went through the edge of the clear coat. That mistake cost a $750 repaint, a week of delay, and a lesson I still teach. Now we measure clear coat thickness before any polishing job. If the number is below 1.5 mils, we stop.

So, to answer the question directly: Does car polish remove clear coat? It can, and it will if you're careless. With a thickness gauge and a sensible polish schedule, it's safe. Without those, you're gambling.

So Which Do You Choose? My 9-Year Rule of Thumb

By now you might want a simple "factory or aftermarket" answer. I can't give you one universal answer, because it depends on the vehicle and the customer. But I can give you the rule I use:

• If the vehicle came from the factory with the feature group, match it with OEM parts when possible.
• If you're adding a feature that was never on the build sheet, consider aftermarket—but verify fitment and ratings against the specific VIN.
• If the job involves clear coat, measure it before you polish. Period.

And one more thing, especially for small shops: don't turn away a one-part order. I used to treat running board installs as "too small." Then a customer who came in for a single TRD board last spring came back this winter for a full Hertz audio system. That small job turned into a $2,200 install. A customer who needs one Ranger trailer hitch receiver might be the same customer who needs a backup camera, a stereo, and a leveling kit next quarter. Treat them like a client, not an inconvenience. Small doesn't mean unimportant. It means potential.

If I remember correctly, the highest-growth part of our shop came from the small jobs we didn't dismiss. I want to say that order was for a $140 running board, but don't quote me on the exact number. The point stands.

Also worth saying: this was accurate as of early 2025. Parts, tariffs, and factory options change fast, so verify current pricing and availability before you write a quote.
