As for washing methods again a much debatable subject, I dont use the 2BM, as it has too many flaws, Grit guards dont actually hold the grit at the bottom of the bucket, most of it is suspended in the foam.
I prefer the Multi Mitt method it's far safer, faster, and more efficient.
Wash mitts, I use Chemical guys Green Noodle wash mitts, these are very soft and dare to all paint finishes.
Shampoo.
Bh Auto wash. Very versatile, cleans extremely well and only 10ml needed max in your bucket.
Works also very well via a foamer or cannon.
Garage Therapy One-maintenance. Very Susdy and lubricated 20ml per wash.
LABOCOSMETICA Semper, again very similar to Garage therapy.
AENSO pure Shampoo is equally good.
Sf, BH Autofaom is among the best IMO.
Detail driven Supplies SF also fantastic product
AENSO SF also especially good
PRE WASH
Detail Driven Supplies Citrus Prewash 20/1 for average soiling 10/1 for heavy soiling.
Bh Surfex HD, APC very similar dilution rates to the citrus-pre-wash and great results
Wheel cleaner
Bh Auto wheel. Very good and can be diluted upto a max of 1/1 for maintenance.
Garage therapy wheel shampoo is great and Sunday
BH auto wash also a great versatile shampoo.
Tyres and plastic
Carpro Pearl neat for tyres and rubber trims, dilute 1/3 for plastic
1/6 for interior.
Faom cannon
Autoabrite is a good cannon although is top heavy and falls over easy enough
Detaildriven supplies wide mouth cannon is the same price, fantastic cannon with a wider opening to pour products into. Foams very well and doesn't fall over.
QD
Garage therapy
Carpro Elixir
Wowo's QD
Koche Chemie FSE.
Both work very well and great as a drying aid too.
Sealant.
If your after quick and easy.
Spray and rinse products
gyeon wetcoat
CARPRO Hydro 2 Light
CARBON COLLECTIVE
Long term sealant
Wowos Crystal Crystal sealant V3
And use either spray and rinse sealants to maintain or a good QD.
glass cleaner
Angel wax Vision
Carpro Clarify.
GLASS sealant Angel wax H2GO
.all of the above I have personally used and tested against dozens of others and found these to be my favourite.
