I was just screwing around with the sandpaper on my old motor. This is dry sanding because my bucket of water froze. I started with 600, then 1000,1500,2000,2500, and then mothers. This was on coolant manifold. Turned out like chrome. Then I started to do the tunnel. Just a small part. You have to go finer then 1500 for mothers to work. This was all by hand too. I'd say 2500 and then mothers if doing by hand. 1500 would still show scratches after the polish. I still want to try that chemical guys compounds to see what happens. Yes, a DA sander would help. Took 1/2 hour to do an area like 3" by 3". And this is an area with no rivets to go around so I wont even touch around the rivets with less then 1500. I will finish sand with 2500 and then try the compounds with my da polisher with wool blend bonnets. Or just use mothers and call it a day. We may get snow this weekend so if I'm going to do this, I'd better start tomorrow. You know what might work really good? Not sure what you call them but they have triangle heads and you can sand with them and cut a nail in half with them. Both sleds are pretty much ready for testing so maybe I will do this. Its gonna suck but at least 1 side of tunnel cant be that bad, can it? I found any aluminum polish I tried just removes the oxidation so you need a very nice surface to begin with. What are you using for polishing wheels? Size also?
I will post results if I get ambitious enough for this. Just have minor wiring issue on wildcat to take care of. (tach and tach light quit working)
Finished my bodywork today!
I just read sleeved cyl thread and you mentioned Bacardi. I was a beer guy. That would be the perfect thing for polishing the tunnel, lots of beer. I haven't had a drink in 6 months now. Still want to but was hospitalized twice in 2014 from it. Probably could have gone more had I known what the problem was. Mass gut ache that would last for 3-4 days and then just go away. I thought it was food poisoning. Turns out it was acute pancreatitus. Worse pain I ever had, suppose to be way worse then a bad appendix.(never had that). I could drink again but I don't ever want that pain again. Last time in hospital I was going into shock from the pain. 5 IV's of morphine didn't even help but 3 IV's of something else took care of the pain but was there for 5 days. Nice watching 4th of July fireworks from hospital window. I was getting bad though, 18+ beers a day everyday. For 20 years. Not as much at first but over the years, I drank more and more. I have no idea what made me write this. Probably just the thought of polishing the tunnel is a good beer job. I guess I'll be wet sanding "dry".
