Advice I was given about Poorboys Wheel Sealant:
Apply first coat, leave for 15 - 20 mins, then buff off.
Apply second coat, leave for 30 mins, then buff off.
Apply third coat, leave overnight, then buff off.
You will find that with each coat, it gets a little bit more slippery
Once the coats are on, it's just a simple matter of taking a microfibre and giving it a quicj wipe after a days drive until the next proper clean.
Hope this helps
