Thanks for that post, seen no end of nasty peeling hand rails and spindles after owners have just slapped a coat of gloss over the stain without sanding, let alone the sealer/block. Its enjoyable to watch their faces sometimes, when you tell them it will work out cheaper to replace rather than start again
Unless that is they fancy doing the rubbing down, some of them start but soon give up after 1st day, especially with turned spindles...
Zinsser BIN is available in Screwfix btw, save you a search
