Gel coat spider cracks in fiberglass fenders?

[heathmorrish]

Has anyone else here come across this problem? Did Ranger fix it?
My boat and trailer hasn't even hit the two year mark and I already have cracks in my gel coat on my trailer?

i assume its from rocks being flipped up by the tires,might try putting a under coating on the underside of the fenders

You just have to wait till they finish the cracking phase. My 2009 reached that in 2013 and haven't cracked anymore. I've been waiting on them to structurally fail and I'll replace them with aluminum or stainless. Hasn't happened yet. Just gelcoat cracks. Make sure the fender to trailer mounting bolts stay tight. If they get the least bit loose, the fender vibrates more and it cracks more. Gelcoat cracking/blistering is not covered under warranty but I would ask.
