Need to sand off rust before painting with Rustoleum paint spray?

janesylviaAugust 3, 2014

Do I need to sand off any rust before painting the front metal door with rustoleum stop rust paint spray? Can I use coca cola or white vinegar to remove the rust instead of sand paper?
Thank you very much.

Think of it as a car.
Sand to remove as much as possible, without penetrating beneath the metal, dust off, wipe with paint or lacquer thinner, prime, sand, prime, sand with a rust inhibiting primer, sand, remove dust and paint.

Do the process in a single, consecutive time frame.

Better yet, have it blasted with walnut shells or a similar media(even fine sand is too coarse) and use an automotive primer/paint.

I've used that paint before---the finish over rust was terrible. It sometimes worked, sometimes not.

A wire brush the size of a large toothbrush is better than sandpaper.
