My Boxford has finally moved up the list of priority list and is in the process of being overhauled and retrofitted with Linux cnc.
Its almost stripped but not sure how to refinish it so looking for options. ideally i want to send it out for blasting and powder coat but think it might be too big and pricey.
What are the brush/roller enamel paints like ? can you get a good finish and do they last?

You can certainly get a bad finish - I can attest to that. Mind you I can only pick up the right end of a brush 50% of the time. What I'm saying is, you certainly have to know what you're doing and prep well. They do last well though (at least my dried-on drips refuse to leave the machine).

I've had some reasonable results painting stuff myself, but the most durable results have always been when I've been able to dry the paint at elevated temperature or used 2 pack formulations.

The 2 pack I've used is polyurethane - great stuff BUT YOU MUST WEAR APPROPRIATE PPE WHEN SPRAYING otherwise you will be really quite ill for a long time. I can't recall the manufacturer of it (was a few years ago), but seem to remember that it came from Germany. I've never used the epoxy myself, but a friend did and said it gave a very durable finish. Some quick googling turned up this stuff which seems pretty reasonable: https://www.taindustrialpaints.co.uk...pular-colours/
I've found drying at elevated temp. helps with pretty well all air dry paint types whether it's enamel out of a tin from the local paint dealer or even stuff in an aerosol: I don't think it's by chance that a lot of industrial finishes are referred to as "stoving enamel". Mind you the weather is generally cold and damp up here, not the best conditions for drying stuff.

You probably don't want to get it blasted, as machines of that era often used a layer of filler to smooth the castings.
Good degrease, sand back, and some machine enamel usually provides good results.Avoiding the rubbish customer service from AluminiumWarehouse since July '13.

Thanks for the advice. I couldn't upload any photos last night but it is a Boxfod 250F with the sheet steel enclosure. the lathe would be fully removed.
However I think have underestimated how heavy it is even when empty and will be a mare to transport and work on.
Probably going to scrape/sand down and then spray or roller with enamel.
Is the tractol paint any good? or stick with Paragon

I think I've established my credentials as a paint drip installation technician. But faced with that I'd be exploring spray-gun technologies. Paragon is good and well established. Never heard of, or tried Tractol.

Tractol is an enamel paint, and traditionally popular amongst tractor owners.
There are quite a few suppliers of enamel paint.
Somewhat topical - https://www.mig-welding.co.uk/forum/...-gloss.110427/
awemawson is someone I know who loves to refurbish machines, and has discussed paint types on at least one of his threads on madmodder if you want to lose an hour or two down that rabbit hole.
For sheet work, I'd either be looking at spraying, or foam roller.Avoiding the rubbish customer service from AluminiumWarehouse since July '13.
