Here are some shots of them stripped; the varnish was failing more than it should have because the last refinisher put some tint in the spar varnish. (Long story). These windows are exposed to the sun and need to be done in a high-quality marine spar that has UV protection, and even then they need to be redone/touched-up every 6 months to 1 year.
I am stripping one set of doors that were mucked up a little and putting about 8 coats of new varnish on, (sand between coats), for best results you need to remove them for this so I take them off and bring them in the garage every day then put them back on at the end of the day. By myself today. My back is a little sore.
