I am bottom painting for the first time and thought sanding, base coat, multi-year ablative was the way to go. A painter suggested to avoid sanding and after removing the wax to go with a self etching primer then a few coats of multi year ablative. Was sold as a cheaper/cleaner alternative resulting in a smoother finish with less drag. Downside is that you are unable to return the bottom to its original state. (I guess you can't sand blast the primer off). Was told that this is becoming popular in NJ with just the need to re-apply a top coat as needed in 2-3 years. Anyone have any experience with self etching primer instead of sanding a new bottom to prep for a different type of base coat? My research shows that this is primarily used on aluminum bottom boats.

Thanks
