It's likely i'm being anal retentive about this but I'm using the trex hidden fastener system and it seems like the boards aren't quite closing tight to each side of the fastener. The trex boards seem to have a bow in them preventing them from snugging up to the fasteners. Granted the gap should be 1/4" and i'm more in the 5/16 - 3/8 on some of these gaps but i'm concerned that these small differences will add up over the 24 feet i have to go and end up causing me issues as i progress. I don't want an inadvertent fan design. I have a board bender headed my way from amazon but any suggestions would be appreciated on how to deal with this. It's the trex transcend product.
