A quick detailer is a great product. I wash my cars weekly, religiously. I also use a qd after every wash, not really needed but it's something I like to do. Invest in a good micro cloth that lasts. The cheap ones are 'ok' but easier with a good one.
My method isn't exactly up there with the pros but time over effort suits me.
Wash with two buckets. One bucket with soapy suds, something ph balanced ideally, ph will be on the tin so to speak.
I cleanse the car with lime prime. Cleansing is a bit like when your better half (not you Obvs, as man!
.) uses a face wash, gets rid of any old polish/wax etc.
A nice easy polish, there's loads to pick from, try not to get carried away and spend hours looking for one. I like the autosmart range as I get that through work
.
Wax. Again, lots to pick from. Could try a sample pot the dodo juice. About £6 for a 30ml pot on eBay or alike.
Quick detailer. Again lots. I've got done and dusted which is popular.
Sealent. Used instead of wax. Easier to apply and remove imo, well depending on which one.
