When I refinished to mast in July 2006, I pulled off all the hardware and wooded the mast using a heat gun and scraper (that was fun in the 100 degree heat we had here in Oriental).
I then sanded the mast down to 120 grit and then applied the first two coats thinned according to the Bristol manf. instructions. On the spruce mast the penetration was good as we could see it on the lower end of the spar.
The remaining coats were applied at full strength using a bit of the tropical reducer to aid in application as it was 95 - 100 degrees every day and very humid. Those are the facts of life here in NC so you just have to work with them if you have to do finish work in the summer time around here.
Sorry I missed your question before I posted my last.
