R&D Trim Tabs - powder coat flaking!
After just 4 months of use I noticed my R&D trim tabs seem to be flaking the powder coating and its going fast! Just noticed it a month ago and checked again over last weekend only see more powder coating flaking off. I thought it was just my ski but several of my friends have them and all are having the same issue.
Please post if your trim tabs are flaking so I can find out if its just a few of us or not. I ordered mine from Greenhulk back in May/June and I believe these are a new batch so maybe its poor powder coating?..
I contacted R&D and they said it could be due to riding salt water - ... um well it they cant hold up to salt then what's the point? R&D wants me to send them in and most likely wait for weeks until they decide what to do. I don't have my stock trim tabs anymore and really don't want my ski down for a month because of this -
Here are some pics of both tabs:

Not a surprise. Salt requires careful planing, even on the little things.
I wouldn't bother sending them back to R&D so they can fix or exchange. These are not powder coated properly as is most retail powder coating. Once the coating begins to fail, electrolysis kicks into overdrive due to the dissimilar metals.
Take them to a professional powder coating company and request they use a "zinc primer powder" under the black powder.
I've done this to a part where the OEM powder coating failed within 6 months. After done properly, it lasted 7 years before a hint of bubble. Also, when you bolt them into place, don't over-torque because this can cause the powder coating to crush (if applied too thick).

Powder coating durability is grossly over hyped. Even when done properly with zinc primer it will eventually bubble and fail. I have had better luck bead blasting aluminum parts, spraying with zinc chromate primer and painting with mercury outboard paint. when that gets scratched it only affects the one spot instead of eventually peeling the whole layer of powder coat.

Rnd uses really cheap aluminum which doesn't help. Run it raw and clean it well has worked for me.
