Likewise, but I also sometimes use a sealant like Sonax Brilliant Shine detailer which is very hydrophobic and lasts ages. Not as nice a shine as a good wax, (IMO) but I think it lasts longer.
In terms of cleaning the fly sh1t off, I'd start with snow foam to soak it and soften it, then a pressure washer, you want to avoid scrubbing. After that a contact wash with a microfibre wash mitt and car shampoo, the experts use the two bucket method but I'm not an expert!
