I have a snow plow that I intend to sandblast, then RustBlast and RustSeal. I would like to topcoat it with a color that matches the red RustSeal very closely. A few questions:

I want to confirm that if I spray on my topcoat within 6-12 hours (according do your diagram here: http://www.kbs-coatings.com/Flow-Chart--RustSeal-on-Steel_ep_87-1.html) I do not need to sand and etch it as long as I do it within this timeframe correct?

What categories of topcoat paints (a brand recommendation would be nice), in your experience, adhere well. I'm looking for a UV protective option. Are the paints I should avoid?

Lastly, I anticipate 3 coats of RustSeal. Is a quart enough to do a plow or - do I need a gallon (I think around 40 sq ft front/back)? What are the coverages?

Thanks.

Yes. That is correct.

You will want to use a good Automotive Grade or Marine Grade Top Coat.

1 Quart might be enough, but you might want to get 2 quarts to be on the safe side.
