Gel coat

[Scott]

Its Polyester resin with pigment (white).... with the consistency of latex paint....Curing time depends on amount of catalyst added and temp you are working in

Can be sprayed (better for large areas) allowing for a “ smoother” surface .... It can be rolled but the result usually leaves more of an "orange" peel surface which means more sanding to get smooth glossy surface.

Depending where you intend to use it would drive how I would apply it ..... I rolled (with a foam roller) the undersides of recored hatches .... I really don’t care how the surface comes out on the underside.
