Epoxy and additives

Post by Beav222 » Tue May 30, 2017 9:07 am

I have some questions and thought this new thread would be the place to do it.
I was mixing a bog mix and it did this.

I think I didn't put in enough Q cell.
Has anyone had this happen to them??

I've never had that... Sometimes when I hadn't put enough Qcell in it would sag, more of a honey consistency and not stiff enough to support itself.
Sorry, I'm no help!

How thick was the bog mix? Looks a bit runny to me - as you say - not enough Q-Cells.

To quote verbatim the plans I got with my kit:
"You want a peanut butter consistency (smooth, not crunchy) for filleting and gluing and a mayonnaise consistency for filling and fairing". I tended to the thick mayonnaise end of the spectrum, not the runny end.

Make doubly sure you got all the unmixed epoxy at the bottom of the tub. I zoomed into your photos and it looks like (in some areas) some unmixed epoxy around your powder. I always worked on the principle - when you think you have mixed it enough, mix it some more.
