What is the point in activating base coat? I understand that we should do it, but no one explains why.
What activator do you recommend, since many basecoats don't have a specific activator? Can you, for instance, use SPI Universal Clearcoat activator with a Sherwin Williams Dimension basecoat if you intend on using the SPI as the clearcoat?
I have used SPI activator in DBU no problems what so ever
I would strongly recommend it with Motobase too. I have struggled with this exact problem, where I broke through the clear getting a touchup to not wrinkle up and match (metallic) is close to impossible.... I had to respray clear in the area before the touchup base.I've used DBC with and without activator in the past and have no problems with SPI clear adhesion. I thought the re-coat window between base and clear applications is what determined linking or not. But, I now use activator for all DBC base because it made it easier to repair any possible clear to base break throughs and no issues with exposed base wrinkling if touched up.

Exactly! This is a lesson learned the hard way on the Dart!Another advantage to having your base coat activated is making it easier to repair.
I sanded through the clear to the base when color sanding prior to buffing. It was a small area about an inch long and normally would have required a couple of steps to correct, however since I activated the base coat it enabled me to just shoot more clear over the area without it blistering up.
