Fisheyes in the gelcoat?

General Composites Discussions Composites Talk
#1

Have any of you experienced this?

I shot five molds today, all of them fisheyed somewhat. I didnt panic but I did manage to bury them with the next two passes. I can still see them but I doubt it will be visually noticeable from the mold side or finished side when I pull it.

See, to me, wax and spraying of any coating are no no’s because of my painting background. I know this has to happen hear but maybe I went a bit crazy with my waxing (green molds, never pulled parts so I waxed 5 times each) or something in my absolutely clean gun?

I guess I am looking for some of you guys that spray alot of gelcoat to tell me that you have this happen to you and its normal…if not, Id like to know how to circumvent the problem…

i use two rags to wax molds 1st to get major wax off 2nd to finish be sure there is not to much wax left be hind if this is your problem you wont have it on the second part cause your wax will be cured unless you are waxing every part?

be sure there is no moistere in air line

be sure gell is stired well

Also, use latex or other gloves while handing the molds as the oils on the hands will also cause fish eyes.

As stated on the other forum, I have a booklet hand out for the students that covers gel coats problems and trouble shooting. It is a little too long for me to type it out here…maybe I should make a complete package of the composite hand outs and sell copies of them…:confused:
