And not using a sponge is a start.
I use a sponge and I dont have any problems ?
i just my car as a daily but wanna keep it clean as i can and wondered what people use
Start with the wash media and get your technique right for a few weeks.
Maybe start with something easy to use and simple, like Auto Finesse Tripple.......Its a great paintwork cleaner, fills swirls and does add some protection.
Then look into buying a wax or sealant to sit over the super resin when your budget suits or funds become available....
Theres allsorts of things you could buy, visit cleanyourcar.co.uk and add a few things to the basket and post what suits your budget in here - people will tell you where to go from there.
Start with 2 buckets, a wool washmitt and some shampoo, also a drying towel. Maybe invest in a small wheel brush and some wheel cleaner & a spray bottle too.
Then look into an applicator pad, microfobre towel and some sort of paintwork cleanser or all in one product (Auto finesse tripple would be a great start), some tyre gel - Megs endurance - (with an applicator for that too).
Then consider buying a wax or sealant to prolong that protection.
