Hi,

I had stripped the paint from two frames. Neither of them had that much rust on them to begin with but I applied a coat of this rust remover to be sure. I followed the instructions on the bottle but it seems to have ended up attracting even more rust.

Am I using the wrong stuff?

When I first applied it appeared to be working, but after I washed it off (on the instructions), the rust started to appear.

Thanks in advance for any advice.

Hard to be certain, but my best guess is you didn't dry the frame quickly or well enough. You might try drying the frame with towels as soon as the rinse is done, followed by hitting it with a heat gun (or even a hair dryer).

Are you going to prime and repaint yourself, or are you taking the frame to a powder coater?

A sandblaster with fine grain abrasive doesn't leave any rust, if you have access to one.

If it's just surface rust, then knock off all your can with a wire brush. Use a metal primer that your paint says is compatible with it and then paint your bike.

I'm going to paint this myself, although I was just going to go with the metallic look, so just some anti-rust/varnish on top of the frame.

Thanks, for all the responses. Good to know it's not a major problem. I can get back to it now.

OK, so as soon as you turn off the heat gun or hair dryer, whip out the primer spray can and get to work. Read the labels, of course, but I think you've usually got 48-72 hours after the primer dries to get the first coat of paint on. After the first coat's on, you can continue or come back and hit the previous coat (that you left to dry for a week or two, I know how that goes!) with a light touch of 1200 abrasive to roughen the surface before the next coat.

Depends on the climate/season you are in. Some of the local sandblasters will do a quick primer coat minutes after blasting because visible rust starts the same day here. With any rust removal from bare metal or chrome plating, it is best to coat it the same day. Some primers are not rust blockers either so get to painting pretty soon.

Thanks so much for this advice, makes it all very clear and avoids me questioning myself at every step
