I used to just wipe a car down quickly with a MF and sometimes QD after polishing. But after having some bonding and streaking issues with LSP`s, I now wipe with IPA/water, or sometimes give the car a wash.
I first noticed the issue with Opti-Seal. I thought it was OS that streaked, until I tried it on a car where the hood had been wiped with IPA, and I noticed the streaking was only on the parts not wiped with IPA. But it seems OS actually bonds ok even with oils left after polishing, it`s like the oils just moves to the top of OS. It was worse with e.g. DG105, a few times it was like this sealant wouldn`t cure, and when wiped off would just smear. But after wiping with IPA or washing, I haven`t had issues with any LSP.
