I was given this

mipa corrosion sealer


I'm using it to treat a few small rust areas under the car, I will grind back to bare metal as much as possible and then brush on two coats of the above followed by mipa etch-filler HB primer and then some wax oil stone chip, Is this OK!

also is it OK if the mipa corrosion sealer goes onto the other bare metal surfaces and the surrounding primed areas?

Cheers in advance
