Odd swirls

[Saular]

Hello I am polishing a motorcycle gas tank and I have a problem I wet sanded and compounded the whole tank and it turned out great I polished the top side and it was perfect. I went to polish the side and after I finished a couple passes I noticed there were odd looking scratches. I thought maybe something got into the pad so I cleaned it and rinsed it. I did another pass and it is still having the same issue. I don’t know if my pad is bad or I have another problem. I will add a picture

Hi Saular,   

I would recommend trying a different pad.  Something smaller than a grain of sand can leave a mark like you are showing in the picture and finding it can be a real challenge.  Once the pad has been thoroughly wash and left dry it is generally easier to find something embedded vs when it is still wet or damp.   Sometimes you won't find anything at all because it comes out with a thorough wash or just falls off when dry.

Agreed with Ray. You might also consider checking the paint depth now that you have sanded, just in case.

Those are sanding mark pig tails.  Was it wet sanded by machine?
