Polar Rust Converter Spray - Rust Converter for Metal - Black - 500ml

Excellent product, I have tested on a rusted surface. Before and after 24hrs pic is attached. I have scratched the painted surface with a piece of metal just to see if there is any rust underneath, but surprisingly it has done a really good job.

Very impressed used on lawn mower deck after repair, no. Rust yet

Used this on a chassis prior to wax oil coating. The coverage is excellent, and it dries extremely quickly 5-10 minutes then recoat. A very good quality finish. Will definitely buy it again.

Seems OK, but unlike other rust convertors it is black and you cannot tell if it has converted the rust. Time will tell, but I may go back to Kurust for my next rust convertor since I can see the effect. Good for underbody rust conversion where it can't be seen, but no idea how it copes with stones, gravel, snow, ice, etc. Reasonable price.

This product does a great job of converting and covering rusty metal. It leaves a good surface which takes finishes well. Needs to be ventilated well.

Great paint. Goes on really well and looks great!

Great product, worked well. No clogging of nozzle, and a good fine spray, without drips, whilst spraying the under body of my car. *****

Doesn't go as far as you would think as it does require more than one coat

Excellent product! Dries fast. Controls rust good.

I like how this product gets really good coverage, I did a few light coats on truck frame, seem to soak into the steel really well

This is my first purchase of Polar paint product. After using five full cans of the Rust Converter, I have some perspective to share, both pros and cons. First the cons, only one really: - The mechanics of spraying were a little disappointing. Although all rattle cans suffer from limitations on spray angles/orientations, the Polar product seems more limited than brand name competitors. Imperfect orientation is somewhat unforgiving. If you move the can out of true vertical, even a little, spattering, and near-only aerosol dispensing occurs. This is easy enough to deal with for most applications in which you can manipulate the item being painted, but for horizontally flat surfaces, it's tricky. The limitations are perhaps exacerbated by the tall cans- making it more difficult to maintain good angles on flats. The pros: - Large, 17 ounce, cans hold lots of product so you can achieve excellent overage. - Product dispenses evenly (unless angles are off), and covers well. It's not thin and "watery" like some rust converters so it is not prone to running/sliding and requires only one careful coat. - Coated areas dried quickly and to a durable finish- I scrape at it after dry and it held great. - Cured coating took top coat nicely leaving a smooth, consistent finish with no fish-eyeing or irregular surfacing. - So far, so great! I did minimal prep (quick descaling and acetone wipe) to some rusty railings, steps, and furniture- all outside in high humidity/wet areas. It's been several weeks and there is no visible rust or sub-surface "jacking." Last note-- I had a concern with another Polar product that I purchased and the manufacturer/seller was FANTASTIC at resolving the issue quickly and ensuing my satisfaction. Polar seems to be genuinely concerned about the quality of their product and the perspective of their clientele. If you've got a project that needs rust conversion and/or paint, give 'em a shot!

Works as advertised just need bigger cans lol.

Great product and great price 👍
