The paint on our heavy panelled exterior front door has cracked along joins
between stiles and rails, as well as along the edges of some of the panels.
I spent much time last year on preparing the door for painting, including
filling all the crack lines with car body filler, but the (moderately)
immaculate finish I then achieved has been marred by cracking has recurred
in a similar fashion to how it was before.
Presumably this is because of expansion/contraction, and "working" of the
different parts of the door against each other. (?)
SWMBO is agitating for me to remedy this, in order to reinstate the finish
that was in place when I finished the last round of work, but I'm at a loss
as to how to achieve this without the same problem showing up again within
months.
Any suggestions? I've been trying to think of ways I can improve the
stability of the door but haven't come up with anything that's practicable.
