Darlene,you make a good point about reliability with polyesters.Unfortunately,there's some poor quality resins out there,and people should be wary of resins that are called all purpose,or boatyard resins.
Usually,they are low price poor quality resins and they shouldn't be confused with high quality resins that are far superior.
I guess i tend to forget that,as i work for someone that only sells high quality resins,and i forget that there are some people selling inferior product.Thanks for bringing that up.
