I,m in the process of cleaning and resealing a driveway for a customer , this guy made a right hash of it doing it himself  2 years ago , sand and sealent all over the chamfers of the blocks   I think he tryed sanding while it was still wet , any way 6 hours later I've got the sand and excess sealant off the blocks using a turbo nozzle  but I've noticed the sealant is still glossey in places , Will this cause any problems when I reseal using Resiblock ultra

Yes you need to abrade the blocks as the resiblock does not "soften" like acyrlic sealers so you need to provide a key to aid adhesion. see the other thread but I do it with a rotary

no - in a word, resiblock say belt sander so you need to be quite aggressive
