Hi guys,
Been skinning for quite a while but now I've stumbled onto something new. I was doing a pair of doorsills using 400 gsm cloth. I applied the first coat letting it go to a full cure and then applied the 2nd coat ( epoxy laminating resin + fast type hardner) with sanding cause I felt the first layer may have been too thin.

2nd coat went for a full cure and then I started wetsanding it ( 400 grid ) After getting it all even, I saw white marks all over the panels, nothing new but this time they remain visible :-( Wiped it down with acetone but even then I can still see them .. Do I need to sand down even more or did something go wrong here ? Please advise :-)

Okay, seems to be something wrong with the 2nd layer. Went crazy on the parts with an 80 grid, till it almost hit thecloth, worked slowly upward to 400 again and the white haze now seems to be gone ... will require a lot more elbow grease but they'll turn out fine eventually :-)

Not sure on what went wrong though .. don't think I screwed up the mixing ratios .. oh well, all well ends well
