Sanding...

Ben036 · 01-June-06, 07:25 AM

So I've been sanding this old comptuer case down real good. This is only my second case to sand and I'm having some issues with it. The first case I really didn't sand well. I ,just got all the paint off, and then I painted it again. This one I've sanded with 60 grit, 80 grit, 150 grit, and now I'm going to move onto 220, but I'm noticing some weird discolorations in the metal. Anybody know what this is?

Looks like it's just part of the metal... Where are you trying to go with the sanding? Are you trying to get it to shine without paint? If it were mine, I would paint it first, then use 2000 grit to colorsand in-between coats. Then, after you have some base on and some clearcoat on, use some rubbing compund and buff out the scratches that the 2000 grit creates.

In no way am I an expert on painting, but the above is the steps I have taken to get the best results (in my opinion anyway) so maybe someone can help you out a little more.

I was going to see if that was a possibility. I thought It woudl be cool just to sand and polish it down to a nice shine, and then just clear coat it.

What I would recommend would be to find a color that closely matches your case, and then colorsand it and eventually buff it to shine. If all goes well, you should get the effect you want.

Like a metalic/silver color?

Sn0wMan · 01-June-06, 09:50 AM

Definately. You can buy a can of silver or metallic, and then colorsand it to a mirror finish. The end result will look nice.

BTW I like your spam sig thing. Great idea

Any Reccomendations?

I would go with a metallic, depending on the look your are going for. It is mostly personal preference and as long as you take your time, you can make any color look good.

BTW here is a link for some pretty cheap sandpaper if you need 2000+ grit. http://www.onlineindustrialsupply.com

What Exactly do you mean by that? Cause I've spend a lot of time sanding, and that discoloration only shows up in some spots. Is this to say If I keep sanding...alot more..the entire case will turn that darker shade, and not the shiney Reflective ligher shade?

You wanna go beyond sanding, your gonna end up in the realm of polishing and you need more than fine grit sandpaper for that. I've only done polishing on a small scale and i used toothpaste, but it still took FOREVER. Heres a guy who polished his entire shuttle case. Toaster.

Yes! You've solved this yourself...

First, I've heard NOT to use a candy apple type metalic paint (you know the ones with the flecks in them) if you're going to sand because it apparently wrecks the paint's effect.

Also, about the polishing. A while ago I went into Part Source looking for rubbing compound and the guy showed my a polishing compound my Mother's. He said he put it on his dremel and used it to buff some kind of metal painted tray for his computer. Anyway, he said it took the paint off and shined it to... then he pointed to his watch and said it looked a lot like it when he was done...
I dunno, maybe it's useful?

You want a buffing kit to bring the metal to a shine .
you'll need a large capaecity set for a electric hand drill,cause a dremel tool type kit would take forever.

Then you seal it in clearcoat to preserve the finish.
