Hello everyone,
I make cabintes (wardrobes, desks, side tables etc) using commercial plywood (not water proof). I would like to paint them (oil based or water based). Here is what I am thinking:
1. Sand the surface by 80 grit sandpaper.
2. Apply filler/putty.
3. Sand again by 180
4. One coat of Primer
5. Sanding by 180
6. First coat of oil paint (using spray gun)
7. Sanding by 220
8. Second coat of oil paint
9. Sanding by 320
10. Lacuqer by spray gun.
Reason I want to use lacquer is to give gloss and to make paint more durable. I don’t want my paint to be easily scratchable. Am I going the right way?
Regards
Sanjay

First, DO NOT think about sanding the plywood with 80 grit. That will blow through the veneer in very short order. Plywood typically comes sanded to 180 grit, approximately and you shouldn't need to sand before finishing. Clean off dirt, don't try to sand it away.
Start with primer. I would apply 2 coats of a shellac based primer such as BIN. Then sand with 180 or 220 taking care not to sand through the primer.
Spraying oil based paint is problematic unless you have good spray booth facilities to deal with overspray before it bounces back to the surface or coats the spraying area with a sticky mess. Oil based paint dries too slowly to be a good candidate for spraying.
Finally, you can not overcoat paint with lacquer, the strong solvents in lacquer run a good chance to destroying the paint. Besides, oil based paint is more durable than typical NC lacquers. If you are equipped to safely spray catalyzed finishes such as conversion varnish, you could use a pigmented variety to paint your cabinets with very durable finish. You would have to use the primer system specified by the manufacturer of the conversion varnish.

It takes a lot to get Steve going but you're breaking all the rules. You need to do some serious reading -
I would have even taken points off for spelling.
