Default Rim (Sawblade) Polishing Question - Experienced Reply Requested

I know there's tons of posts about polishing rims but I have a question for people that have polished their sawblades.

Where I'm at? I've stripped the clearcoat and grey paint from the rims using aviation stripper. I'm now ready to start sanding the machining grooves out.

Question: :confused: When you polished your rims did you sand/polish the rough sections in the "tooth" of the sawblade? It appears to me that this area is going to take many hours to get smooth. I'm wondering if it's better to simply re-clearcoat or paint this area?

Question: :confused: What paper did you start with to get the grooves out? I'm planning on starting with 400 wet, then 600, 1000, 1500, then polish.

I'll post some pics when I'm done.

Thanks!

Sanding out teeth can be a real pain. A couple of things that helped me was a hand held sander for small spaces. Thier about $30.00 at home depot. Using a dremel a lot and I found plumbers sand paper when I was almost done. This comes in a roll about a inch wide and in different lengths. By securing the ends to sticks or what ever. You can pass this through the slots and saw back and forth. Worked the best of all I tried in getting the rough down.
On the flatter more open spaces of the slats and the face, using a orbit palm sander will help.
Its a lot of work so make sure you clear coat the rims when done. I had good luck using just the spray cans of rim clear by dupli color.

My 88 rims has that kind of roughnes that you are talking about , when I polished them I left that roughnes and painted it with very light grey finish and for the rim , I removed the clear coat then started sending with 320 grit wet paper to remove the machineing lines than with 600 wet then with 800 wet then with 1200 wet after that I polished and :cool:

:iagree:

You can skip the 1200 and even the 800 step if you have a machine buffer. I use 600 then 3M fine cut on a 7" heavy nap pad and an Hitachi variable-speed grinder.

Nice rim. I can see your reflection in it. :)

I think I'll try something a little different to see how it turns out. I'm going to lightly sand the rough areas to get most of the roughness off. Then try polishing what's left. If my theory holds true it will be somewhat shiny but not as shiny as the rest of the rim and should look Ok. If it doesn't work I can still paint the "teeth" or sand some more.

If I only had 4 kids I could give each one a rim to do. :cry
