I read that link info too, several times, and got confused as a result. I can read IRS code and understand it but could not decide which product to use on my Cheoy Lee 36. However, I did come away with the understanding that "blush" does not have to be sanded but is washed off instead.
My sense is that the vendor really does know his products but could use a little work with marketing and promotional writing. I think he probably has a pretty good product and a decent price but the web site kind of puts a reader ill at ease.
So, I think it will be MAS expoxy for my
rig, probably later this week or early next week if I can get the bottom ready. There is so much pox from a previous barrier coat that was poorly applied that I will sand as much will come away and then fair the worst of it with expoxy before rolling on the final shield.
Hope you job comes out alright if it has not already been completed.
