Do you use a dedicated sealant for rims like AF mint rims or PB wheel sealant? While there are many out there in all product ranges, these two are the mostly used 'dedicated' sealants for rims I believe. While other paint sealants work fine on rims as well but they aren't very durable to the metal.
Locally, I bought my friend Armorall rims sealant spray (i think around Rs. 500 in a small sized aerosol spray). If you look at its youtube demo from a 3rd party reviewer, you'll be amazed by its repellancy on how the guys throws all sorts of things at it (dirt, oil, rail dust and what not and it all slips away). I got it from Al sheikh autos ISB but it was a limited stock and last i checked he couldn't get hold of it again. Metro may have it, if not then check in Lahore. My friend used it on his 5 spoke alloy rims and loved it (100 kms per day travel) and it offered great durability to him as well. Can't say how many applications it had but for the price and availability locally, a great value for money.
Using from your own stock, you can dilute you Klasse AIO either 1:1 or 1:2. As Klasse is water based so it dilutes really well in water and put it in a sprayer just for your rims cleaning purposes whenever you wash your car. It'll also leave a nice coat of sealant on it for a reasonable duration of time providing you both cleaning and sealant in one go.
