I just finished painting
my 81 Scamp
Ensolite about 45 days ago after an intense scrubbing with Fantastic. Per recommendations that were posted here I used:
Zinnser Perma White
which is an anti-mildew interior paint.
Very pleased with the results, I think it looks better than the ensolite probably did new. It has taken a good bit of abuse with reinstalling all of the components and it has held up well.
The nice thing is if you keep a quart handy it is easy to touch up over the years.
Pic will show the old ensolite and the new paint:
