Advice on painting old machines - total newbie.
Hoping to solicit some advice from people who have more experience painting than I do, I literally can't think of a time I've needed to paint something so the Woodfast bandsaw restoration I'm doing has me scratching my head. I've used a paint stripper to get it down to bare metal and everything has been bathed in Evaporust so I'm good there but I have no idea on primers and paints etc. Hoping someone can answer the following queries.
Application - Painted on or spray cans? I was initially going to use the Rustoleum 2x primer and satin paints but I saw some people use a brush and paint on the finish for old machinery. Pretty sure spray cans will work better for me but I don't know anything about the Rustoleum stuff, it's just what I saw at Bunnings.
Primer - After doing some research I see there are epoxy based and etching primers, again no idea what I'm doing here but it looks like etching might be the way to go considering all the nooks and crannys that will be hard to scuff up. Brand and type recommendations would be awesome.
Paint - Only real requirements is that it's black and preferably not a gloss finish, was going to get the Rustoleum Satin 2x but I'm open to suggestions. I'm more confused on the acrylic and enamel decision for this job. The adjustment knobs and wheels are going to be colour matched cream to the colour on the badge, friend recommended a place locally that is supposedly really good and can make up spray cans. I suppose I could get the black paint there but I don't even know what to ask for at this point.
Pics below so you can see where I'm at on some parts.

I notice you are writing about Black plaint but I think you mean Matt paint?
Paint finishes come in two basic types glossy or matt and variations in between the two an intermediate version sometimes being called Satin.
Enamels are hard wearing and fast drying.
Epoxies are also hard wearing but dry slowly.
Because its an Al casing you should probably use an etch primer of some sort.
Even the brush applied stuff dries quickly
If I were doing it and you think you might do other machines in the same colour I would go for a spray applied enamel, and make sure it is properly thinned out so it flows properly into all this gussets. Tins give you a lot more paint for your $$ than spray cans.
If you only intend to use the one colour for the same machine then spray cans might get you there.

On reading it again I agree. Black machinery - that's no good as it will show the dust.
OTOH it could remind you to turn on the dust extraction.
Now that I mention this it might be a good ides to install a dust extraction port in the lower cabinet before you paint it.
I'd cut a hole big enough to fit a 4" PVC floor drain fitting as it has a touch of a bell mouth about it and glue it in place from the inside. Once you apply paint it will look original.

Thought about black being problematic with dust but it's just more incentive to keep things clean in my opinion. And I'm actually planning on installing dust extraction into this, there's a slot in the bottom of the case that I'm going to make a dust port for so hopefully that should cut down on dust outside the machine.
So at this point I'm looking at etching primer and enamel paint, will be painting this in stages out the back so drying time is going to be key if I want to lay down a decent number of thin coats. Unfortunately don't have a compressor so I'm going to be limited to spray cans if I'm blowing it on.
I had thought about powder coating but I have a feeling that will get pretty expensive, I've managed to keep the total cost at to $280 at this point so I'd rather not blow it out too much.

Hrmm my curiosity got the better of me and I decided to start looking for discussions on powder coating prices in Perth, I actually think it might be feasible price wise if I take into consideration the chances of me screwing it up the first time (pretty good chance hehe). Seems like there quite a few places in Perth so the prices are quite competitive, will send some pics and dimensions around and see what they come back with.

One thought on the powder coating. Some of these parts need to be masked off and only have a coating on certain portions, is that possible with powder coating?

The one thing I like about painting something yourself is that if it is for a working machine or rather one that gets used quite a bit and you scratch it or chip the paint ( and you will, it's only a matter of time ), then you can touch up the paint. A lot harder with powdercoating.
