Getting ready to put primer coat on. All wire brushed. What is the best way to get rid of oily residue?

Lacquer thinner works. They also make paint prep stuff that is a lot like lacquer thinner.

Mineral spirits. It has a longer working time than lacquer thinner.

Castrol Super Clean goes by just Super Clean now. I bought 2.5 gallons for $18. It was sitting right next to another product called Purple Power. The net said both are good products but Super Clean is stronger. I got the Super Clean. I'll give it a try.

I find when hanging small parts hitting them with brake cleaner right before painting is a lot less tedious and works better than wiping them with something. only thing is a can goes fast

VM&P Naphtha makes a good pre prime wash on metal.

Well I think tomorrow is the big day. Got the tractor stripped down as much as possible. All has been wire brushed and hit with the needle scaler, blown with air, and washed with Super Clean and air dried. It is looking pretty good.
I have never used a HVLP gun before today. Ran a lot of water through it today "painting" cement playing with air flow fluid flow etc. I think I am ready to try some primer tomorrow. It is a sandable primer so if I screw it up, I can take it off and try again.
Water sprayed good at 20 PSI with fluid nozzle open about 1/4 turn. Had a nice elipticle pattern. I am assuming paint will be a little thicker. I have filters once I mix it. I think it says 1 pint reducer for 1 gallon paint. I am going to mix in smaller batches though. Anybody have any tips?

I personally would use a self etching metal primer or epoxy primer on cleaned metal.
Sandable primer surfacer is not designed for priming bare metal. Save it for a smooth sanding primer over body work and first prime. When you get a smoothed surface ready for finish paint seal it with a primer sealer before applying final color coats.
You can't hardly do enough prep work before shooting final color coats.

I agree with Ken. For the first primer coat I'm a big fan of self etching primer. After that I'm OK with whatever primer you want to use.

Looks like a HF sprayer. Used several of those and also have an expensive one and even though they lay it down differently I'd be hard pressed to say the more expensive gun paints better than a cheap one from HF. You'll do fine.

I, personally, would wait until this terrible humidity in our area subsides, before spraying paint.

Looks like you're making good progress!
I agree with the others, use a self etching primer on the bare metal. Then, if you want to get picky, prime again with sandable primer. I did spray on a layer of sealer over the primer before painting, but I don't think I needed it. Had some guys tell me the sealer is more to keep old color from bleeding through. When I painted my 45 a few years ago a barely used sanding primer. The expensive self etching primer laid on really smooth. I was getting tired of painting and decided it was good enough on most places. I don't have a perfect show finish, but it turned out pretty good.

PVC pipe and 2mil plastic. 13'x10'x7' 8 3/4" 3 ways, 4 couplings, 12 10' 3/4" Pvc pipe, 20" box Fan on one end and furnace filter on other. Seems to work. Having trouble holding plastic to floor. Might have to wrap in 2x4. Sat 2x4 on top of plastic but it keeps pulling out. I'm guessing I should wait 24 hours before top coat?

Read the product Data.
some primer can be coated after 1 to 2 hours later some work better later also depends on the temp and humidity.

I use brake clean, dries fast, leaves no residue, spray it on a rag and wipe down, painted an RC tractor with spray cans in 2003 after wiping down with Brake clean and it still looks good.

Most problems can be solved with the proper application of high explosives.

Primer was dry this morning. Lightly sanded and put first color coat on. Will check tomorrow ans see if it is ready for a second coat. I noticed a lot of orange paint on the floor and on the corners of the walls near the floor. Kinda hard to spray the under side of the tractor. The angle of the gun just does not make it easy. I like the results so far.

I am thinking two coats should be enough.

Looks good! I like your booth too. Two coats should be fine, as long as they were 2 decent coats. I usually do a light duster coat at first, followed by 2-3 decent coats. Knowing when to walk away is an art.

Interesting, what kind of paint are you using that you wait so long for the second coat.
I always thought that you came back on with another coat when the previous one tacked up.

That's how all the paint I spray works.

That gets me every time- I want hit one last spot and the bam, it runs... Best to do several coats. As you mentioned prior, the bottom is hard to cover good.
