I've used West for 30 years - not continuously.
just recently I had the clear hardner (more expensive - no blush) turn color after 2 years. Whats the point if it is supposed to be clear?

The cost of the clear with it going bad when I had 1/2 a can has gotten me to thinking about changing.

Non- blush is very worth it in general.

Don't know what I am going to do. Besides look back at all the previous discussions.

I used system 3 for one boat and it worked fine, I just didn't want to wade thru all their options for picking a resin, and having to learn the tricks everyone takes for granted.
