Continuo from previous post .
Up to removing old hardened surround impregnation . Entire procedure is already explained here, but I’ll try to illustrate it and explain more thoroughly .
What you need is :
– Alcohol (Etanol) 96%
– cotton rug
– small container for Alcohol
– small brush ; that sort which is bad for any painting , but perfect for purpose – around 10mm wide , plastic threads – so it is semi-hard ….. perfect for applying some force , which we really need here .
