I found an older post on someone asking what westanding was. Just to make sure what it is.. It's just sanding it while pouring water over the car every now and then? Is this REQUIRED? Should you be using more than 1 grit of paper?

 

It is usually done after you get a fresh paint job. You can do it on any paint job just make sure you don't cut through the paint ( excessive sanding in one general area). If your car has been painted a few years back and you want some shine, go with a 2000 grit and buff. After a fresh paint job 1000-1500 is the most common grit used. Run water over the designated area while simultaneously sanding .

 

you can also just dip the paper in water as long as the paper stays wet.

 

Oh wait I thought this sanding process was done for prepping your car to BE painted.. What does wet sanding do? sounds painful to new paint..

so now about prepping for paint.. If I were gonna sand the whole car down myself and primer it.. What type of grit(s) do I need to do that? thanks for clearing some of the confusion so far..

 

Yeah in 3 stage paint jobs from what I understand, they wet sand the base coat before they throw on the clear, and then wet sand the clear .

do a search " wet sanding "
a lot of info...
