Sportster front fender: wet sanding
The paint wasn’t too bad on the fender, so I just wet sanded it with 320 grit wet/dry paper.
I put some water with a trace of soap in an old squeeze bottle, some people use a garden hose, but you have to watch that you don’t ding the paint with the nozzle. Others dip the paper in a bucket, but I have found that grit (sand, dirt or whatever) can contaminate the water and leave scratches.
I like to use a piece of thin plastic foam inside my paper to prevent finger marks from getting sanded in to the paint. Cut the paper in half, then fold it in thirds for hand sanding.
Afterwards, all the water must removed from any crevices, otherwise, it may drip out when you painting and ruin the job. Get the nozzle of an air gun as close as possible and repeatly work over the whole part.
Here you can see a few drops forced out from under a rivet by the air pressure.
