ok you decorators zampa, gcol,etc, l am going to tackle my outside windows since we have desent weather and the job needed doing like 2 years ago. The windows have pane bars with 8 small windows making a window frame, all the windows need doing. My question is from start to finish what is the right way to go about this. How do l go about rubbing the paint work down ,do they need rubbing down, what sandpapers are best for this or is there a better method .Will they need undercoating or just use one coat.If undercoating is needed what is the best to use, and what is the best gloss to use.Anyone who's done these type of windows before how did you tackle them.
