I have just found that Resin Research kwik kick epoxy is fab for my sand coat (use other resin usually with better strength but a bugger to sand). However when I add additive f at about 1% i get a nasty large patterned orange opeel surface. use without and it’s better. What should I do to get a no fish eye sand coat. I always get a few large dime sized areas that repel resin. Is this contamination? oil from hands or what?
ampreg 20 by SP systems - it may give better results due to it’s viscosity being much higher than RR - i am awaiting the RR data sheet from Seabase UK to compare with Ampregs figures… It has just been replaced with Ampreg 21 which I am yet to try
