I used Boysen Sanding Sealer first.

More precisely, I think that is Boysen Lacquer Sanding Sealer.

It does not look like Boysen makes Sanding Sealer.

In contrast, Ace has Sanding Sealer but not Lacquer Sanding Sealer. The label for Ace Sanding Sealer says "Do not use under lacquer. For lacquer, use lacquer sanding sealer."

The label/website for Boysen Lacquer Sanding Sealer does not say whether it can be used under oil-based coatings. (In general, Boysen and Davies labels are content-free.)

Yeah it's Boysen Lacquer Sanding Sealer No. B-1254.

What I did was use this on MDF then spray coated it with Epoxy primer and 2 x Auto Acrylic Paint / 2 x Acrylic Clear coat.
