Q: Is RustBlast safe if it is gets on wiring, rubber, etc. during the process of using it on a car chassis?
A: Yes, as long as the contact is casual and the RustBlast is rinsed off with water, RustBlast should not affect your wiring and rubber components.
Q: If I have new steel, do I have to let the RustBlast stay wet on the surface for the minimum of 30 minutes or can I do less time?
A: New steel is usually very smooth, so we highly recommend leaving the surface wet with RustBlast for a minimum of 30 minutes so that you have an ideal surface profile when you go to apply the RustSeal. Also, remember to keep the surface temperature as warm as possible (within our temperature guidelines) because the warmer the RustBlast is, the more effective the RustBlast is.
Q: Can you use RustBlast on aluminum?
A: RustBlast works very well on aluminum to etch the aluminum allowing excellent adhesion of paint.
Q: I have a pellet grill of 10ga steel, will rust blast work on it to be top coated with a stove paint?
A: Yes, you can use RustBlast on steel to etch the surface in a high temperature coating application. We do recommend when rinsing the RustBlast with water to lightly rub the surface with a scotch brite pad which will remove the zinc phosphate that is typically left behind by RustBlast. You want to do that because zinc phosphate is not rated up to the temperature required for high temperature applications.
Q: Can this be used prior to using your rust convertor?
A: Yes, you can etch a rusty surface with RustBlast and then used KBS Rust Converter after the rusty surface has been etched with RustBlast.
Q: Do I need to clean off the powdery phosphate prior to coating with paint?
A: RustBlast is designed to leave behind a dusting of zinc phosphate after rinsed with water and this zinc phosphate aids in the adhesion of any coatings that are applied to the surface.
Q: Can epoxy primer or etch primer go over rust blast?
A: Yes, you can etch a surface with RustBlast and then apply an epoxy primer, etch primer or any other kind of coating. RustBlast etches the surface and creates an ideal anchor pattern for the coatings to properly adhere to the surface.
Q: Does Rust Blast affect adjacent painted surfaces?
A: RustBlast will not affect a fully cured painted surface when RustBlast is used according to the directions.
Q: What color is RustBlast?
A: RustBlast typically does have a dye in it. The reason: So a difference can be seen between RustBlast and KBS Klean as these two products are typically put in spray bottles for application. The color of the dye we use depends on what is available so please do not assume that one color of RustBlast is better than another color. The dye is simply in there so you know you are using RustBlast and not KBS Klean (which is clear).
