Matt, does this mean that there has been a change in thinking on the subject of varnishing? I'm sure I've seen a number of posts on this forum that recommend leaving the epoxy a few weeks before applying paint or varnish and Chuck said in one of his posts that he waits a month. I think the reasons are to be sure that all blush has surfaced so it can be removed before application and also to make sure it's hard enough.
Maybe someone has discovered that we don't need to wait after all?

Laker 13 - christened and slimed (just).
Laker accessories underway.
According to my enquiries, it is ok to go ahead with the varnish, and impatience got the better of me. I took a couple of piccies after ther first coat.

That is one really great looking boat and you did a wonderful job of making it and finishing it , it looks like glass. She is a BEAUTY.
I give it 30 days before varnishing it , this way I can paddle it , scratch it up , get it dirty and find out how it handles....... Then a light sanding and some varnish and it is as good as new. The one epoxy supplier said it can be used after 72 hours but takes 30 days for the epoxy to reach the final curing stage....... If there is a blush to it , so be it , the sanding removes the scratches and all the rest. Then the varnish as the final protective coat for the boat. Any scratches after that , a light coat of varnish and it is back like new.

I followed up with another vendor, System Three, and they said at the bare minimum, the epoxy has to be cured enough to be sanded with creating any gooey little balls. So if you sand it and it makes dust, you should be ok.
Waiting longer (up to 5-7 days) can be beneficial to ensure that cure stage but be aware of amine blush issues.
