    My prinsu rack is kindalooking like a pile of shit. Took off the windbreak and found some pretty good oxidation, rusting out of the bolts as well as had one bolt shear on me.. tried the ‘scrubbing bubbles’, no luck.. tried miracle pad thing, nada... plus the sheared bolt has kinda screwed me with getting it back on

    Stainless fasteners would not be a good choice. Cadmium coated would be a better choice to slow down the galvanic corrosion. Adding Cor-ban to the faster would help even more. For the cost of the excursion I would just have a new one shipped to the house. Time is money and this could turn into hours, broken drill bits and a ton of aggravation.

    No loc tite. Other ones came out ok. Harsh winters in alberta but this is a bit nuts and not what I paid for. Have an email into them but they seem to be a lot bigger shop then when I originally bought it...

    The surface looks like aluminum oxidation due to long term exposure to the harsh elements. It will take some elbow grease to remove it. Try 180 grit sandpaper or steel wool then finish with aluminum or metal polish. Clean, rattlecan aluminum primer then rattlecan satin black krylon paint or rustoleum bedliner. Sorry OP but it's 4 yrs old so why would a vendor warranty this? I can see if it was maybe a few mos old but you got 4 yrs out of it and it does not seem difficult to repair.

    You could always get the dimensions of the existing cross brace and buy another. Youll have to tap the holes though.
    https://www.grainger.com/category/m...|Smooth~~Number+of+Open+Slots|6&filters=attrs

    I would try easy-outs first to get that sheered bolt out first though. Youll need a way to securely hold the piece though like a bench vice.

    $20 ATE Pro Tool 8 piece Easy Out Screw Bolt Extractor Set
    https://www.amazon.com/ATE-Tool-piece-Screw-Extractor/dp/B0002UJNWE

    Drill a tiny pilot hole through the middle of the bolt. If you ground the bolt flat, it will help stop the drillbit from wandering on you. Then its light taps with a hammer and vice grips while turning the extractor counter-clockwise. Should get that bolt out in a jiff. I would, however, try to vice grip or channel locks on the exposed threads and back it out that way before you attempt to drill it out. It just depends on how much time you're willing to invest on this. Heat works too, just avoid holding the torch on the aluminum for too long as aluminum melts at roughly 1200F or 650C. Heat the aluminum and not the bolt and it should come out. Some spritz of thread penetrant could help with that too like WD40 or PB Blast.

    As for the mold issue, some elbow grease with a scotch brite pad and degreaser would help clean up the salt/mold look. Youll want to treat for corrosion like others have said up above. When you get the time, dissamble the whole thing off your truck, clean and prime the side rails and deflector, treat the threads/threaded parts with a rust inhibitor. Use a small dab of anti-sieze on the threads when you reassemble the kit and it should last you another 10 years.

    Put antisieze on the rest of the bolts.

    If this was a 6 month old rack it could understand this being an issue but 4 years?

    Just time for some new fasteners and a little TLC. Maybe anti-seize the bolts next go round. All it takes is some rain and the galvanic corrosion process has started.

    I dont expect a replacement, however having your own product look like crap is not really a great idea... Not wanting to take the rack fully off the roof, as i have a sneaking suspicion that the bolts to roof are next to shear..

    It's entirely up to you OP but if you are suspecting that the bolts are about to shear, I would take the time now to replace them. You never know when you might be off the beaten track and have a failure. You can mask off the roof and treat for corrosion if you dont want to completely remove the rack. It's a cost base balance though, do you risk failure down the road or risk shearing a bolt under a controlled environment where you might have access to tools? You could let the mounting hardware soak for a bit in thread penetrant to give you a fighting chance in cracking the holding torque.

    Most aluminium will expand 5x faster than steel. I would heat to around 400 degrees Fahrenheit add oil. Let sit until fully cool. Then heat again to 400 and try to budge bolt.
