Hi /diy/ I'm hoping to paint up some weights I got off craigslist

>>998218
No rust paints dont work
use a wire wheel or a wire brush and remove all the rust before you paint.

You can do almost anything with the power of flex seal!

Buy a small tin of Por15, a pack of cheap brushes, and wire wheel the rust off. Then clean the weights really well, let dry and then brush the Por15 on. They'll look brand new and never rust again.

Wire brush and hammer paint will make it good as new

Just put mineral oil on it. Wire brush won't keep the rust from coming back, and can cut grooves that rust will spread to. If that's some anodized coating to prevent further rust you'll just take it off and allow for more rust.

Mineral oil, on the other hand, helps keep oxygen out, so it'll slow the rust if not put it on hold altogether. Once something starts rusting it's going to keep rusting if there's even a small amount leftover.

And mineral oil is food safe, which is good because hands touch weights and your mouth frequently when you're working out.

If you don't like my idea, try a pressure washer before a wire brush, it could remove the rust without creating the little grooves. I had luck with a car wash pressure hose on an old engine that was rusted to hell. I didn't believe it would work til the old timer across the street told me that's what they did at his shop back in the day.

>a wire wheel "creating little grooves" in a fucking cast iron weight.

You have obviously never worked with cast iron, or wire wheels.

Clean them to get all the oils off let dry. Go ahead and remove the heavier rust with a wire brush then liberally brush on some Jasco Prep and Primer or equivalent rust converter. I've tried Por15 and didn't care for it but that's just me.
Next day the rust should of turned black if not do it again. Then paint it. Flex Seal sounds like a good choice.

3 sets of 8-10 reps or until failure

Take a paint brush, dip it in vinegar, brush it on the rusty areas and leave it overnight.

The vinegar should have neutralized the rust.
A brass wire brush will take care of the rest.

Wipe everything clean.

Now take a paint brush and brush some linseed oil on the weights. This helps protect any bare metal from corroding.
Put on a second coat when dry. Apply more linseed oil every 6 months to a year.

If you can get the weights warm before brushing it should both penetrate better and dry faster.

Honestly, there's no reason to even deal with that rust beyond just a few strokes of a wire brush + WD-40.

Op you can do this:

to clean the metal, then use a metal primer or a metal paint and primer in one. Use pic related afterward to make it look like the weight or use another metal oil based paint.

this
wire brush, rust converter, prime it and coat it (enamel)

OP here I wire those fuckers, washed em down and hit them with some ospho. Friend told me to use that. Gonna prime tomorrow
