Cordless drill sanding bit?

[M-EGT]

Hey all. I bought a bumper at a junkyard and I'm looking to sand it down, and then paint it. I figure I can save time using a bit for a cordless drill to sand it? Any recommendations?

Do you have an angle grinder? if so you can use something like this http://www.milwaukeeconnect.com/webapp/wcs/stores/servlet/product_27_40028_-1_683180_192523_192327

Or for your drill you can use this http://www.fleetfarm.com/detail/3m-...earch&gslfah&gclid=CKWAvOnfkbgCFY0WMgodMRUAhw


the grinder will be faster if you have one

Thanks. I just have a cordless drill.

I use mine mostly in my drill press, not so much on the cordless. If you have a hammer drill or one big enough to give you a side handle, then maybe but I imagine it would be pretty awkward. That's how the wire wheel is, you can control it but you have to fight it some.

Mine either came from HF or northern, some el cheapo but it works. I mention it because mine specifically came with only very coarse sand paper rolls.

Thanks, I'll try it out and see how awkward it is.

It is Very easy to gouge a plastic bumper (cover) with a sanding disk. Is the bumper plated steel? You may be better off using a hand sanding block or try a friends DA electric sander with 120-180 grit. No need to remove all the paint--it's your best primer

Nah, its plastic.
And think so? Are you saying I should just spray the color over the existing paint, or primer over the existing paint? thanks

Unless it is damaged- just hand or DA wet sand with 320 wet/dry paper.

An automotive epoxy primer sealer is sprayed next or apply a SEM aerosol primer sealer.

Then Wet sand with 600 wet/dry with a sanding pad to smooth for top coat.

Unless you are applying paint with flex additive- let a body shop paint it. Otherwise it can easily crack when bumped.

do not use a spinning, round sanding drum or disk on a drill, in an attempt to sand a plastic bumper. you will not have an acceptable surface after trying it.

if you are broke, hand sanding something that size wont be a big deal.

also, take retrosbuilders advice too, plastic bumpers dont take well to regular paint.

Forget the silly drill..Buy a small pack of 320/400 automotive sandpaper. fold it in half 3 x and wet sand with water from a hose.. you will have better results than a drill sanding pad..

OK, I'll do that. I was hoping a sanding drill bit would save time, but if the results won't be very good then I won't.

And I'm ordering paint online so it will be matched to my car.

2nd this. I wouldn't use a circular sander on it. The paint will come off pretty easily by hand. I'd use the fine grit that they mentioned, too.

Scuff and shoot. Make sure you get a flex agent for the paint. You can buy some shade in spray can with flex agent already added.
