That'll work. You might find some tight spots where the brush will work well for literally stuffing some ZR into a crack.
As you are using out of the bulk container keep an eye on consistency and add some thinner to keep the viscosity where it will level by itself. Solvent flashing off from the can will result in the ZR getting thicker without maybe even realizing it's happening.
Great painting weather we've got going, huh?
