Need some schooling on buffing out minor abrasions and some small scratches in clear coat

Type of polishing/buffing compound

which buffing power tool and pads would you suggested

Procedure the How To, and the do’s and the don’ts best method

The abrasions’ and scratches aren’t bad enough that they wouldn’t buff out with hand buffing
I tried the hand buffing but the “By hand power” doesn’t work well for me with my arthritis

And way it’s been a long time since I have buffed anything and would appreciate some of the pro’s
Here to sort of give me a little refresher course.

Thanks
Randall

The tools and materials needed depends on the extent of the damage and how much you intend on using these products.

If you only have a couple of small areas to repair you can use a small amount of 2000 grit wet sandpaper (http://autobodystore.net/Merchant2/merchant.mvc?Screen=PROD&Store_Code=ABS&Product_Code=3mimpwetdry&Category_Code=SM) by hand then a 3" backing plate (http://autobodystore.net/Merchant2/merchant.mvc?Screen=PROD&Store_Code=ABS&Product_Code=ST300&Category_Code=T2) with some 3" foam pads (http://autobodystore.net/Merchant2/merchant.mvc?Screen=PROD&Store_Code=ABS&Product_Code=3inpad&Category_Code=T2) on a drill to do the polishing.

If you have larger areas or want to polish then entire car I'd recommend a Makita Polisher (http://autobodystore.net/Merchant2/merchant.mvc?Screen=PROD&Store_Code=ABS&Product_Code=MAK9227CX3&Category_Code=T2), a 6" Backing Plate and 6" polishing pads (http://autobodystore.net/Merchant2/merchant.mvc?Screen=PROD&Store_Code=ABS&Product_Code=SFPADS&Category_Code=T2).

I would probably polish using Sure Finish Polish (http://autobodystore.net/Merchant2/merchant.mvc?Screen=PROD&Store_Code=ABS&Product_Code=SFQ&Category_Code=M3) from start to finish.

Chances are a scratch in factory paint that you can feel with your fingernail won't be able to be removed totally by sanding and polishing without removing too much paint but most that are just light scratches can be sanded and polished out. The heavier scratches can probably be helped but not eliminated.

Lightly sand the area with the 2000 grit sandpaper wrapped around a stiff pad (http://autobodystore.net/Merchant2/merchant.mvc?Screen=PROD&Store_Code=ABS&Product_Code=DRBAF4405&Category_Code=TFSL). Then do your polishing by applying some Sure Finish Polish to the painted surface and go back and forth with your rotating polishing pad to bring back the gloss. I usually recommend starting slow with medium to heavy pressure then, as the gloss appears lighten up on the pressure.

Hello Len

Thanks for the info, I have a 3” pneumatic polisher with the white foam pad and yellow foam par and the wool pad the areas are small areas about 3 to 6 inches in diameter I was able to hand rub out some of it by hand but needs a little more compounding and will try to use the 3” polisher.

If you could fill me in on the process of buffing being I haven’t done any in a mechanical buffing in years
Sad it seems I have forgot so much over the years and could use a little advice on how to like how much compound to use how wet to keep it how lightly to buff pressure wise etc.

I've emailed our January tip sheet that may have some info you need.

When you first start polishing you want to press a little harder and have a slower rotation of the pad and as you get your gloss back you want to lighten the pressure on he buffer.

Make sure the rotation of the pad rotates OFF of any body lines and panel edges.

Depending on the type of polish you're using you may want to dampen the pad first.

Start light and easy until you get the feel for the process, it should come to you pretty quick.

If you have any specific questions let me know.
