Nova Repair & Alterations Update:
Got my Nova back from Seaskin after 5 weeks round trip sent to them from Spokane Wa area. They provided a UPS label for sending to them, $80. I sent the suit without neck or wrist silicone Sitech seals. After some email back & forth to clarify my fit issues (and current body measurements just for reference) and alteration hopes, they proceeded to work on it.
The new/replaced watertight plastic zipper (yeah, giving this one more chance, otherwise will revert to brass if any more issues caused by user/friend error or not) seems to be maybe 1.5" longer over the shoulder than the original. Watertight zipper now goes a fair bit further under and past the outer zipper/cover.
For fit alterations at crotch and shoulders, seems they replaced the gussets with slightly larger panels. The upper torso is now a bit baggier than needed even with my 250gm Seaskin under garment, but I'll deal with that rather than the too-tight issues. The shoulders & chest no longer have the super snug "tuxedo fit" of the rest of the suit, but usable and still probably better fit than any off the rack non-custom suit. From the waist down, the suit is still very trim fit. The crotch room now seems to allow for full range frog kicks, though the leg length could be a bit more... like an inch or so... next time.
I'm not sure why but when done, Onur @ Seaskin informed me he emailed the repair invoice. When I opened the invoice attachment, very surprised to see $0.00 "Warranty"!!! That also included the return 2-day shipping. Wow. Perhaps when they reviewed the suit measurements vs mine (and that I had ordered the 250gm undergarment at the same time) they saw it did not allow for enough room and/or zipper length. Regardless, wow. I don't know of any other suit mfr that would do that. If anyone has any concerns over customer service, let this post be a good reference.
Oh almost forgot, the suit returned with a new set of Sitech silicone seals - neck and wrists :O
