We have old sash windows with rotten sills. I've made good the wood using wood hardner and filled with filler etc etc and now have a presentable finish.
However from past experience I find the paint cracks after a while betwixt wood and filler. Googling around I discover Latex Gloss Paint is recommended - however I think this is a US product - do we have anything similar here in the UK??
Failing that whats the best way to go about getting a lasting no cracks paint finish with glass fibering etc etc?
TIA
