I searched before posting this question, but could find a thread which give specific details on this matter.....Do you need to do a Dawn wash before JetSeal application for proper sealant/paint bonding? I am very familiar with the "Zaino" process but was not sure if it applies to all sealants as well. I have a 09 jet black bmw 335 will be doing a one step with 106FA and would like to use JetSeal for the LSP. Also, are there any sealants out there which are more compatible with the Menzerna polishes? Thanks in advance.
