Two years ago I was using West System with slow hardener, lots of blush... PITA!!

Started using System 3 with slow hardener and MarinEpoxy with slow hardener, no blush at all!
There were times I wish I had the fast, but things worked out!

Water and NO soap is what I have read with light sanding if after 72 hours (?). Soap could leave a residue....

Home built boats, get their personality from the builder... My boat is NUTS!!! FS14, getting wet soon.... Next build; LM18 (Laguna Madre Skiff 18). This is a beautiful designed boat.

Blush can appear I'm a bunch of situations. Temperature and humidity play a big roll. I'm in central Florida and the Marine Epoxy with medium hardener would blush a lot if I used it in the evening. Not so much in the day time. Any time blush appears it needs to be removed, no matter how long the cure. The 72 hour thing only really applies to sanding between laminations, but it's subjective because different speeds and resins have different windows from what I've seen. I usually remove blush with alcohol, I don't like water going near my wood.
Built: 15ft Skiff, 16ft Skiff, Modified Cheap Canoe.....FS17 coming soon!

I’m sure it has a lot to do with the humidity then. Since the weather here in Jacksonville hasn’t been great this week. Thanks for all the help guys
