Hello, I have a hard wood verandah with wooden slats for walking on and wooden handrails. It is south facing so gets the sun and is subject to very light traffic. It was previously covered with Dulux woodstain, some of which I have removed but most of it is still there. I want to apply an opaque covering (probably light grey), preferably easily paintable over with different paint in later years. It needs to look nice and not industrial to please my wife. I am perplexed by the variety of paint you have so need some guidance as to what is best for me needs. Can you help? Thanks, James
