Does the rule of not wetsanding factory paints apply to single stage paints also?

On vehicles with factory paint you are still dealing with approximately the same topcoat thickness even with a single stage style of coating.

So it is a good rule of thumb to follow the same general rules....

Just a reminder: When we say it is not a good idea to sand, we are saying it is not a good idea to sand for the purposes of removing orange peel....However, sanding with the appropriate grit in order to remove an isolated defect would be ok regardless of finish on a factory car as long as you are monitoring the amount of material you are removing.

3) We limit how much sanding is done and with what grit we allow class members to use. We only remove .2 - .4 mils which is well within the specs of OEM factory repair.

Even did the before and after with the QuaNix meter. Only removed about .2 mil overall if I remember correctly.
