Did you make a sample to go along with it as you finished? If so, and hopefully you did, then test it out on the sample first ok?
I'm concerned that with a lot of retarder you may find that if you spray another coat of 50/50 in hopes to blend it out, especially a wet coat, it could react. Again I'm concerned if it doesn't work and you then try to scuff sand and re-coat it could even be worse and crinkle from the new coating or laying open the new sanding marks or both or other. Plus as i stated since you used pre-cat instead of regular NC lacquer, you have to take into consideration your mil thickness as of now. Applying heavy or thick coats especially when heavily retarded, could easily down the road cause premature cracking and such. normally pre cats are not supposed to exceed 4 mils [ 4 thousandths] when dry, that's thinner than a business card, and that includes not just the pre-cat but any other sanding sealers or other beneath the pre-cat. but it's to late to change it now. Boy....next time you have an issue with weather/humidity, don't add the retarder to the finish, instead just spray it with the 50/50 R/T in mist coats to clear up any blushing after the UN-retarded coat is applied ok?
Sorry i can't be of more help as things stand, hope you don't end up having to strip it.
PS: If by chance the retarder does not fix the damage, please wait about a month or so before trying to re-coat ok or even longer if possible, once the finish is hard, then it will be much safer to try and sand and re-coat. But even then thier are no guarantees, especially as i said if the mil thickness has already been reached or exceeded.
