Right now using meguiars gold class shampoo, will switch soon as it's near empty. Sealant was done in january this year. Klasse was used i think. As the car is parked open there is no shade already there are some weird blackish marks which feel rough to touch on one A pillar and some small areas rest is fine. Also roof has weird hand imprints and like something like a leaking glass/cup was placed on the roof. Not sure if that were there when i took the car from luxe, noticed them a while later. After sealant i thought it would be easier to wash the car and dirt won't stick as much but it's the opposite, after rain black marks appear on all sides of the car which are a bit hard to remove. Sealant doesn't bead water too. I think i should've saved more money and gone with glass or ceramic coating.
Sorry to autophile for hijacking his thread, i hope he doesn't mind.
