I would say that would be a problem only if you do not prep correctly. If it is a G8 nut and bolt with high alloy structural washers and a thread locker I'd go with that over a rivet anyday.

I love POR 15 on undercarriages, floor boards, but on a frame it looks like someone base coated/clear coated while they were high. Powder coat the frame and the suspension components, you'll thank me later. Also, POR-15 does not mix well with fasteners, coating a fastener after it has been installed makes it damn near impossible to remove, and coating before installation is not a good idea because if it is on the threads it could cause galling because of how thick it is. Zinc and cadmium to a lesser extent are common coatings for bolts because of how thinly they can be applied and not affect the fitment of engaged threads. Take hot dipped galvanized fasteners for example, galvanized coatings are very thick and the manufacturing process takes into account the extra added thickness. That's why you cannot use non galvanized with galvanized, especially in a structural application.
