There are 2 types of adhesion - mechanical (sanded surface) or chemical. Once a coating is cured, you can no longer get a chemical adhesion. Now, there are some products that will adhere, but you are proably somewhere along the line going to take a risk of delamination and/or quality outcome. Some higher end paint systems have prodcuts your can just spray on over the ecoat, but I still would sand/scuff it. It really only takes a few minutes with a DA to sand a fender and run over the edges with a scuff pad. You can do this easy by sanding it with 180, prime (probably etch prime) and seal if necessary and apply paint. Wet on Wet, no sanding in between. This is done all the time in repair shops on a daily basis.
