Hi Guys
I wanted to ask for those of you who provide spotters how effective are they and for those of you that sell them do you sell much of them?
Thanks
Martin 
Restormate ones (all ive used in my short time tbh).. very effective
Sell them and give them away depending on job ticket etc..
Last xmas for e.g i bought 50 and sold ALL 50,, each day i would challenge myself and at the end of the week keep a running total just on spotter bottle sales! sad i know but it was kind of fun too... i dont charge as much as Mike by the way,,but was making well in excess off 100% of the cost...
I liken them to business cards in a bottle..
Often get asked "have you got anymore best stuff i ever used"...
Regards
Paul
