Hi all. I'm waiting for my order of DG 601&105 to arrive but was wondering if I should use a paint cleaner before applying 601 to remove several layers of sealants and waxes ,Colinite 845 being the last 3 coats. I know #601 is also a cleaner but am not sure if it completely removes Colinite Common sense tells me to use a paint cleaner like Meg.Deep Crystal (step one of the 3 system)to make sure there is no waxes or sealants left on the paint ,what do you think? Thanks. Ken.
