I have been agonizing through prep for solvent borne base/clear paint. The problem is sanding over imperfect flush rivets and imperfect dimple perimeters . Sanding will strike through the primer back to bare metal, or expose the wash/etch primer which the paint maker says should be sealed prior to the finish coat.
Regardless of brand names, wash primer , etch primer etc. need to be covered with a barrier primer before finish coats. This requires a two step repair of each tiny flaw. I am joining the epoxy primer advocates so a “strike through” repair is a single puff of epoxy, awaiting another attempt to feather the edges without striking bare metal again.
Any wisdom you have to offer is welcome![Smiling face with smiling eyes :blush: 😊](https://cdn.jsdelivr.net/joypixels/assets/7.0/png/unicode/64/1f60a.png)
