Default Scuffing Aluminum Panels

I've searched posts on scuffing aluminum panels. Everyone recommends Scotchbrite and WD-40. Dumb question, are you spraying the WD-40 on the Scotchbrite pad and scuffing the panels, or scuffing the panels dry and wiping them with WD-40? I tried scuffing the panels with white viniger and Scotchbrite, does a good job, but very messy. Just looking for a cleaner way to get the job done.

I spray it on the pad, scuff, wipe off excess with clean rags or paper towels.

If you want to get lazy, cut the pad to fit a jitterbug sander. I've done it dry, but wet would probably work too.

Bob, what is the objective of scuffing the aluminum panels? Cosmetic only? or is there some benefit in maintaining panels clean etc.? Rick d (whose panels have just been installed!)

I think Bob and I like the same look, no shine, competition, raw, brutal and no trailer queen. I ran black diamond over my wheels.

It gives you the look of brushed aluminum. As they said above, the raw race car look

I had to take the press-brake forming lines off the 289 grill parts. While I would have liked to just make them smooth, it was very impractical, time-and-effort-wise. Instead, I gave them a fine brushed finish.

For a nice satin finish.....

1 - Scotch Brite pad and NAPA Twin Etch #6879. (stains and dulls the surface).

2 - Use rubber gloves when using the acid and move the pad in a uniform direction.

3 - Wipe down with rag and cleaning solution.

4 - Use clean rag moistened with WD 40 to add a sheen to the panel.

5 - done.

Examples of work:

I used white vinegar in a spray bottle for the etch solution along with grey Scotchbrite. Wipe down with a 50/50 mix of rubbing alcohol and apply a light coat of WD-40.

WD 40 has kerosene which acts as a lubricant and short term protectant. I have always used the red scotchbrite with any cheap liquid dish soap and water mix. Just enough soap to foam up the water/soap mix, the soap is the lubricant. Works just like when you wet sand you use water.

The soap also removes oils and other contaminates.

When you are done and you want the satin look but also want corrosion protection use Alodine 1001 from any good paint shop. It is an invisible conversion coating (chromium etch) that protects the bare aluminum. It has been used in the aircraft industry for years and is easy to work with. Just follow the directions, the great thing is any time later you need to touch up the aluminum you can. Just get out the scotchbrite and repeat the process.

I wondered how long it would take for somebody to dispute this.. ..not near as long as I expected.. ..we do have some knowledgeable people here on the forum....see the below excert from a magazine article

"There are rumors circulating that WD-40 contained Chlorine. We have thoroughly tested WD-40 and this is a falsehood. This rumor may have led to this second conclusion that WD-40, if left on steel or aluminum, can lead to corrosion. WD-40 has corrosion inhibitors that prevent corrosion to metal surfaces. This has been true since it was first created by Rocket Chemical."
