When I bought the 601 I thought it was only a prebonding agent. After using it and seeing how black the app. pad got I realized it has really good cleaning properties. After much reading I see others have commented on the cleaning ability of 601.
I went with 501 because of it's super cleaning...
I recently started using the DG line. My white work truck catches alot of abuse and detailing a 1 ton isn't something I really look forward to , but I try to keep it looking nice.
I chose to use 601 followed by 501. Im really happy with the results so far.
Has anyone else used this...
