Mike's 1973 D22 Complete tear out. From the Roof down!

They are an issue. I simply taped off the thin grill rails with masking tape. Then, I used a sharp razor to trim a fine line along the edges of the grills and coated the rest of the grill with flat black paint.


Here's the tricky part: using 180-grit sandpaper, I carefully sanded the top of the grill lines in one direction to achieve a brushed aluminum effect. It's important to take your time while sanding; a single straight cutting stroke can yield a nicely brushed appearance.



You may want to experiment with 180 to 220-grit sandpaper, depending on the hardness of the aluminum and the finish you prefer.

A 8 hour soak in ocyliac acid will remove any corrosion on that grill

I would really like to see a picture of that outcome..You have an excellent idea!!

My steps would be..
1. Soda blast everything to get it very clean...

2. with the bench top buffer, just polish the edge as you suggested..That is the front edge..

3..Mask that edge that was just polished with tape..Fine cut the tape to the edge..

4. Flat black on everything that is unmasked..

Excellent idea..Thank You Eyez

Maybe some cool fog lights!! 2 behind the grill and 2 on the bumper..

My suggestion would be to use rubbing compound and a buffer and buff it up to chrome. Then mask the horizontal bars and paint in between the bars black.

If you brush or sand your grill, it's important to be aware that it is sensitive to the sanding process, which should aim for a bright and uniform finish. Make sure to sand in one direction only, and proceed gently as you go. If you discover an effective grinding method, please share your approach.
The only luck I've had with polishing is with the stuff below. If you get lucky this stuff can really polish

Next spring, I will be painting the RV and clear coating the grill, so I have several months of preparation ahead of me.

That Grill really looks Nice..Excellent Job!!    

I am going to take a long look at this bench top buffer..

Look at all the options down at HF..I have all the grill pieces..the corner wall pieces..Exterior door and windows too..

So maybe that bench top buffer is the way to go..Lifetime investment

Since I have been using 6AN fittings for the fuel system, I bought this filter for it all..

I know it is a China import..But I hate to say that I am impressed..

All aluminum..that screen is 30 microns..That is the filter that goes to the pump..Keeps frogs and crickets from getting to the pump..

Then out of the pump in goes to that big spin on filter that has a water separator..then to the carb..

I painted the second white coat on the front face pieces..So I guess it is time for the aluminum trim next

There is a lot to do..Not only the grill but the 4 wall corner pieces..I haven't even looked at those yet..

After it is buffed up, spray a clear on top to keep it nice?? Or just buff again later when it tarnishes ..??
