Bugs are bad in the south right now. The front end of my new Wrangler is covered in dead love bugs, etc. i have two layer of BFCS on the vehicle. If i spray a bug remover/degreaser on it and then lightly powerwash, will it strip the BFCS off?
Can't really answer your Q properly as I don't know from BFCS, but...
Most stuff like degreasers/APCs will strip, or at least compromise any LSP.
The 1Z Anti-Insekt stuff (link: 1Z Einszett Anti-Insekt Pre-Cleaner ) is different; much to my surprise it does help remove the bugs without significantly compromising the LSP, usually it doesn't seem to affect it at all. I sure didn't expect to like/use/recommend it, but it really works well for me. I'd at least consider giving it a try.
