Received Aqua clean today & Rust Blast to get some fresh metal prepped on a Custom motorcycle Im building & just finished using both products as directed on a front fender & a set of handle bars, They were kept wet for 10-15 min with the Aqua Clean & scrubbed usung a fresh moroon Scothbrite & Rinsed, Left to dry& then treated with the Rust Blast for 10 min & then rinsed throughly & left to dry, As its drying Im getting goldish colored patches on the front fender & not the solid greyish color it shows it should be, Again this was fresh sanded metal with no rust & Im just trying to get a good surface before a Expensive Custom paint job is done, Why would it get the tarnishing instead of the nice grey etched surface it is suppose to ??

Tried recoating bars again & kept wet for 20 min with the Rust Blast, Rinsed & watched the Flash Rust develope again ?? Everything states the Rust Blast keeps metal from Flash Rusting & protects it up to a month, What seems to be the Problem here, There is no way I want to shoot epoxy primer & do a expensive paint job over flash rust which is all I keep ending upwith ??

Ron, keep the surface wet with the RustBlast. DO NOT LET IT DRY ON THE SURFACE! This will only cause a zinc buildup. After rinsing with water, used compressed air (if possible) to blow off excess moisture. We also use a clean dry cloth to absorb the excess moisture before allowing to air dry thoroughly. This will minimize the discoloration. What temperature are you working in? In either case that "discoloration" or "flash rust" you"re seeing is perfectly fine to apply epoxy primer over. With that zinc on the surface it will bond like crazy.
