hi guys anyone used this with weber?? i know weber do an accelerator but just thinking its prob best to use a retarder instead as iv got to do this job in two weeks when its going to be shorter days less light and dont want to rush trying to scrap before it gets dark as this job is a bitch and is above a super market enterance so its not your easy just pump on and scratch job so care must be taken and all that WITH ALOT OF PEOPLE IN AND OUT ALL DAY.I have been told with this retarder i could put it on say by 11.am and scrap back roughly 11am the following so as always would just like to ask if any of you have done this AS THIS WOULD ALLOW ME TO DO THE JOB AT A SAFE PACE.
