They are "normal' if that is what one typically only EVER sees on parts. From the MFG's perspective, it may be an acceptable flaw but it is stilla flaw and just represents weakness, even if it is weakness between or within a few fibers in a 2 or 3 k strand....but- what if there are more serious voids in between plies...? makes you think what else is going on that the you cant see.
If Vorsteiner spent more time making the part "flawless" then they will be doing about the same techniques only changing a very small amount of what it is they are doing but that change in technique should not result in justifying passing the cost in $$ to the customer when this change should be done on their own nickel. It's part of the MFG process! They know what they're doing btw. they dont have to change either because the parts are passing throught their QC and QA and people still buy their parts.
Keep in mind that the pinholes shown in this thread could very well just be solvent popping within the primer coating having nothing to do with the composites. I know first hand that vorsteiner does a tremendous amount of constant redevelopment to offer the best product at a competitive price. They will take this issue (believe it or not even a small issue that someone discusses directly with them in person or over the phone) and adjust accordingly. Smearing someone on the world wide web typically is not the way you normally accomplish correcting what i consider to be fairly normal, installer correctable flaw.
