What causes ripples in epoxy resin?

The seal coat, which is applied in small amount, prevents the air bubbles and occupies the empty spaces on the surface..
How do you fix fisheye in epoxy?

Why is my resin wrinkly?
The mechanism of wrinkle formation by a resin paint is thought to be as follows:A polymerization reaction proceeds in the layer after the first application, and the stiffness of the layer increases as it cures . … Exposure to the organic solvent causes the polymerized first layer to swell .
What causes fisheyes in epoxy?
Substrate contamination is the most common problem that causes fish eyes and pin holes in epoxy seal coats. Dust, dirt, wax, silicones, even the oil from your fingers when touching the part prior to sealing with epoxy will deter epoxy resins from laying flat and curing with a perfectly smooth surface.
