Anyhow, I did manage to put the primer oil on the cedar siding of the porch today and tomorrow, hopefully, will be able to complete the rest and start the stain/finish. The products I am using are made in Germany and imported by Bioshield Paint in the USA. They are not made of petroleum, but from plants and trees, and are biodegradable. The stains contain earth pigments for colours. It is a pleasure to work with these products and the inhalation of such presents so much less damaging vapours than conventional wood stains used more commonly in North America. How does it look so far?
