Hi. if I wanted to use the rust blast as a base and then a rust converter over, do I still need to rinse it before the converter ? and what would happen if I didn't rinse it ? 

Yes, you should always rinse RustBlast to neutralize the acid and to prevent an excess amount of zinc phosphate left on the surface. When RustBlast is rinsed, the correct amount of zinc phosphate is left on the surface which aids in the adhesion of the coating that is being put on the surface. If you do not rinse, you can leave too much zinc phosphate on the surface which can hinder the adhesion of the coating that us being put on the surface including KBS Rust Converter (should you decide to go that route).

Please let us know if that helps and if you have any additional questions.

Thank you for the feedback. I've been struggling with creating a proper procedure for our rust elimination. I own a large snow removal company. we have about 75 units between pickup trucks, tandem axles and wheel loaders. each one goes through a restoration process that we remove as many pieces as possible. Grind off as much rust as possible with wire wheel cup grinders and needle descallers . Then we spray on the rust blast and apply a brushed on rust converter. primer and final paint.  I have not rinsed any of the units we have used the rust blast on. should I be concerned? can you help me with your professional recommendations of what exactly I should be using to achieve the best results possible and is there a larger size container we can purchase ?

Thanks   

We have snow removal companies all over the country using our proven products because the investment is worth it for the long term protection of their equipment.

For snow removal trucks (and the like):
1) Wire Wheel and Needle Descale.
2) Clean with KBS Klean (Can be put through a pressure washer).
3) Etch all areas well with RustBlast.
4) Coat with RustSeal. Thin coats and at least 2-3 coats.
5) Coat over the RustSeal with BlackTop for any areas that are exposed to sunlight.

This will give you the best permanent finish that will protect against rusting and will allow for easy cleaning of your snow removal equipment.
