Fleetwood Advanced Satinwood Base: Uses?

Hi all

From what I'm reading can Fleetwood Advanced Satinwood Base be used to paint doors etc without a primer/undercoat?

From what I'm reading here it seems to suggest that previously painted surfaces dont need primed, just sanded?

Can I use it to paint doors that have been varnished, just by painting directly to sanded/clean/dry surfaces?

From the tin:

PREVIOUSLY PAINTED SURFACES
All surfaces to be painted should be clean, dry and free from loose
and flaking material. Glossy surfaces must be rubbed down to
provide a key. Stir well before use. Avoid overspreading. For best
results use a good quality synthetic brush. If using a roller lay off to
avoid pin-holing

Thats a mainly water based solution which my experience, allows the oil to come up through the finished coat eventually.
I would prime first. fleetwood do an excellent primer/sealer called Bloxx It.

Thanks dok golf, it goes against my old and seasoned grain not to prime before painting. I was just wondering has technology quickly passed me by.:D
