Brightwork in the Sun
Our trawler, Last Tango is blessed, cursed, with lots of brightwork on deck.
Our product of choice is Bristol Finish, though that is the the subject here. There are other quality products, but you must understand their application parameters before you complain about the quality.
Bristol and many others claim they can be applied in 100 degree (F) temperatures, and in direct sunlight. Both are true statements, but don't combine the two...
At 0600 the air temp was 80, caprail temp 80. I applied 1 coat Bristol.
At 0930 air temp was 87, caprail temp 93. I applied a second coat.
At 11:20 air temp was 91, caprail temp 162! Application is postponed till later in the day...I will shoot the temp at peak and it will be over 175 degrees. It's amazing anything survives this all day, every day. And it's no wonder products fail rapidly if you're behind on your PM work.
Rule of thumb: If you can cook bacon on it, it's too hot.. :-)
