Hey was hoping someone might have some helpful advice. We have been working on infusing a carbon fiber part and we want a super high gloss wet look. We are using Zyvek product GP mold sealer and release and an inmold high gloss clear coat with UV protection for Duratex. Anyway we were advised from our supplier Nexeo to use the #6 release but we had all kinds of fisheye problems with the clearcoat so they recommended wiping down the mold with mold cleaner to reduce the surface tention but no luck. So we now have tried the #3 release and still are getting fisheyes in our clear coat. Yesterday we pulled a part without the clearcoat but are finish just wasn't glossy enough plus we had alot of what basicly looked like fisheyes in our resin. We are using a vinyl ester resin which we buy from US Composite out of Florida. We have done some hand lay-up with this same resin and carbon fiber and the finish has been real glossy for us. We found that the Zyvek #6 when used in our hand lay-up mold even fisheyed with our resin but the #3 when wiped with aceton came out supper glossy but pulled a bit hard. Anyway we are stumpped and not getting a lot of advice from our rep from Nexeo as of yet. Anybody have some helpful tips or advice as we are about to pull our hair out. We have been fighting with this for a very long time and just not winning.
Thanks
Mark

Hello
Isn't this the technic used in the Bricklin cars. It was just aweful. Two dissimilar materials that had different expansion rates. The bodys were all wavey and got worse over time.I believe hot tubs use the same process. But John Deer must have done testing. (I hope)
