Been reading the threads on sealants as i'm considering using them on DD's. While they obvisously last longer than waxes and i don't care if i have a slightly plastic look on these cars, i've read a couple of inferences that they can be infiltrated by tree sap giving the user a serious headache. And bugs of course comes to mind. Can bug jiuce penetrate the sealer staining the surface? At least one of these vehicles will be parked outside under a small tree 24/7. Is this risk a with sealants? I understand that so many are waxing on top do we even know this answer? TIA, great forum.
