A couple of weeks ago I asked about ROS disks on which the abrasive was bonded with stearates and was advised against using them because of the deposits they might leave.

Could this be your problem?

Good luck
: Well, I went to bed last nite and the last coat looked fine. When I awoke
: this AM, it had fisheyed again, not nearly as severely, but bad enough . .
: .

: I received an email from someone who laminates for a living, and he said it's
: almost always caused by oil contamination - I was so careful of what I did
: this last time, I wouldn't have believed it. But here it is. Any ideas?
: Here's my prep & coat sequence: 1) Sanded hull thoroughly - Scuffed
: completely by sandpaper everywhere. Not one pit or depression left in
: surface.

: 2) Washed hull with dishwashing soap and water using scotchbrite pad. Rinsed
: and dried thoroughly.

: 3) Let sit for 1 hour, warmed hull with hot air gun, let sit for another
: hour.

: 4) Opened new West roller pkg - Cut roller in two. Used new roller pan cover.
: Applied epoxy exclusively with new roller. Worked epoxy pretty severely to
: assure it was wetting surface.

: That's it. To say I'm hesitant to do it again is an understatement. I doubt
: my resin is contaminated, it worked fine on previous coats. The only other
: things I cannot be sure of are the roller and the roller pan cover -
: And/or Florida's heat & humidity. The picture is of the most severely
: affected area. The larger pits or depressions are the problem, not the
: dust . . .
