Rub Smooth First Layer and Applied Second Undercoat

Today, we rubbed down all the pieces of our Skylight framework, making sure that any dribbles, drips and sags were removed. It was a slow process and it took most of the day to process 43 individual pieces, and we also applied more wood filler, especially on knots as these were upsetting the curing process of the polyester resin coatings.
We managed to apply a second undercoat layer to all the critical areas where the triple glazing will be fitted, to ensure a good air tight seal on the surfaces.
Tomorrow, in the afternoon, we will check this second coat, do any further rubbing and then start applying the final white glossy layer.
