Hi I just used Rust blast for the firest time in some freshly sandblasted car patch panels. I followed the instructions to the letter, with the exception of Aquaclean as it says it isn't required on freshly blasted metal. Now I have some areas that have the white residue, some areas that look as they did before (although a darker shade of grey) and some areas of brown which I am guessing is flash rust. It does in fact look exactly like the ***-** example on the website comparison. Is it better to agitate the rustbast with a bristle brush or similar (I just painted it on with a paint brush). I am not comfortable simply painting the Rust seal over this flash rust, as it is worse than when I started. Any ideas? Cheers, James.
