EF Mizuha Sealer and Heat Shield Top Coat Set - 1-Component Water-Based Urethane Waterproofing Material

I purchased a three-part set for concrete roof waterproofing paint, but the primer and top coat were unused and I have leftovers, so I am selling them.

This is a set of primer (sealer) and top coat.
How about for DIY?
