One tow on slushy roads in an open trailer or hanging out of the back of a short box truck can cause this. if it was towed in the open the aluminum will show signs of dulling and possible white spots coming up. It will just look older than it is all over. Also sometimes parts are not painted quite perfectly either which can cause this if it is only the one spring? Wouldn't bother me any

This sled came from Rockland marine near Ottawa? 

Here is what google ai spitts out to the question are snowmobiles usmca compliant.  Lord knows rules are changing daily.  Time will tell.   Yes, snowmobiles can be USMCA compliant goods. Specifically, sub-heading 8703.10 (snowmobiles) in the USMCA rules of origin allows for an RVC (Regional Value Content) of 50 percent using the net cost method or 60 percent using the transaction value method, according to a commentary from the C.D. Howe Institute. This means that if a snowmobile is produced with a certain percentage of regional value content (from the US, Canada, or Mexico), it can qualify for duty-free treatment under USMCA.    Elaboration: USMCA and Rules of Origin: The USMCA (United States-Mexico-Canada Agreement) is a free trade agreement that aims to eliminate or reduce trade barriers between the three countries. A key aspect of USMCA is the "rules of origin," which determine whether a product is considered to be originating from a USMCA party and therefore eligible for duty-free treatment.    Regional Value Content (RVC): One of the primary ways a product can qualify under USMCA is by meeting the RVC requirements, which specify the percentage of a product's value that must be derived from within the USMCA region (US, Canada, Mexico) to be considered originating.    Snowmobiles and RVC: For snowmobiles, specifically under sub-heading 8703.10, the RVC requirement is relatively lenient compared to other automotive products. Producers can either meet a 50% RVC using the net cost method or a 60% RVC using the transaction value method.    Duty-Free Treatment: If a snowmobile meets the applicable RVC requirements, it is considered to be originating from a USMCA party and is eligible for duty-free treatment when exported to the other USMCA partners.    BRP's Compliance: Bombardier Recreational Products (BRP), a major manufacturer of snowmobiles, has stated that the vast majority of their vehicles are produced in Canada and Mexico and are USMCA-compliant, meaning their shipments to the US are tariff-free. 

Sounds like new units will be tarried coming in this fall, since it contains usa steel and aluminium. That might seem like a bargain if new ones jump 20 percent.
