This thread if full of misinformation.

1. Whether the body is hand laid glass cloth, matt, or chop gun has zero to do with this issue. Kevlar or carbon in the laminate is also irrelevant.

2. The idea that any primer has sufficient rigidity to be structurally significant in a composite laminate is ridiculous. If the composite wants to move, the primer is either moving with it or coming off. EDIT: Print through is not the same as post cure creep.

3. This issue is directly related to the quality of the resin, and the quality control in mixing the resin. If your body isn't stable after a year, you can pretty much bet on it never being stable. Without knowing the specific resin they used, there is no way to determine if your issue is a material defect, or just cheap materials that shouldn't have been used in the first place.

4. Generally speaking (very general) the resin food chain (bottom to top) is cheap polyester @ $25 per gal, better polyester @ $30 per gal, good polyester (like tooling resin) @ $39 per gal, cheap epoxies @ $75 per gal, vinylester (can you say factory five?) @ $45 per gal, quality epoxies @ $100-$800 per gal. The problem with cheap epoxies is excessive flex and post cure creep.
