Wondering if you can help. Just moved to new unit. The wooden window frames blistered in winter. I had to replace the glass because it scratched and pitted. They now need complete paint. Please tell me what I need to do. I was told the tan or light brown oil or paint because of colour will blister. I have ti stick to the light brown. I already have Dulux primer,undercoat in white in oil based I bought from you.would like to use this.
