As the owner of a BX25D, and having read countless threads on this problem, I sympathize with the OP's predicament. Mine stays parked inside and doesn't see any use in the rain for this reason. Hopefully I'll have some free time soon to disassemble the thing and waterproof/seal the cluster before this happens. Thankfully mine had a cab on it for the first decade of life before I purchased it. It really is BS that a tractor can't be used outside without the cluster corroding into uselessness and I'd probably be pissed about it too since it's a well-known problem with a poorly-designed part. Thankfully the forum has been very helpful for me in informing me about the issue so I don't fall into the same hole.
