I bought some woodstain the other week. I chose to seals quick drying woodstain because it’s woodstain that’s quick drying and from ronseals. It does exactly what it says on the tin The only reason I chose this was because of the pervasive tv adverts in the 1990s when I was a teenager. Back then I had no need for woodstain, and very limited idea on what I would want it for, I didn’t buy any until 15 years after I stopped watching live tv (and thus tv adverts). First place I’m going to look for a new sofa would be DFS, again because of the adverts, again from the 90s. How do studies catch the roi over decades?
