where are you based? we can get the local Parex contact to call you..... or visit their website and give them a call (Most of the better render brands offer assistance - the parex guys are usually very helpful and I believe they do their own accelerator......? (TBC)
If you ask at the place you are proposing to get the Parex from, they will advise you of the local Parex guy's details as well.....
There are some Parex users on here, but it is best to get answers from the horses mouth sometimes!
good luck!
