Best rust converter on the market.
on 11 April 2016
A truly fantastic product that can virtually stop corrosion dead if used carefully.
Loose rust should be removed before application for it to work properly. I paint it on using a small brush as it is very watery and tends to run (it is like milk); However, I had no problems painting it on upside down under a car. Three hours after the application, the rusted metal turns dark blue/ black and becomes solid. This means that it can be painted over straight after it dries (3 hours). If it is still brownish, after an hour, apply another coat.
Tip: Use a plastic container (cup possibly) and pour a very small amount to begin with, as very small amounts are needed! Dispose the leftover liquid and do not place it back in the original container (you will contaminate the whole bottle with your brush and ruin the product).
There are other options on the market if you want to paint it faster (reduces waiting time from 3 hours to 15 minutes) but I find Kurust more effective if applied properly. You NEED to apply a topcoat after this.
