I use DG105. I think the main difference between the two is that the DG105 has some/more cleaning ability than DG111(which i think is more of a 'pure sealant' with little or no cleaning ability).
Correct me if I'm wrong, but I don't think it is advisable to use SIP with red pad.
If the paint is in good condition, a lesser aggressive 106FF with white pad would be better combo.
I think the red pads have very little cut and is suitable for LSP.
Jeff,
Thanks for clarifying that Menz does not contain fillers. Can you also confirm that the 106FF that comes in the square bottle is the same exact content that comes in the round bottle? I've seen this argument come up from time to time that they a different.
