I've experimented with blu tack after reading on another forum that people were using it. I've never used a clay bar so I have nothing to compare against, but the blue tack didn't really seem to work - maybe my technique was wrong...
I've been contemplating this myself. A google gives mixed results from no good to it working. I tried some on one of the filing cabinets at work a couple of hours ago. When I ran my hand across the paintwork prior to 'claying' it with the blu tack, I could feel and hear the rough finish. Afterwards the surface felt smoother and made less noise than the part I hadn't 'clayed'.
Who's gonna be brave enough to try it on their car then?
>could i use this as a substitute for very expensive flanalette polishing rags?
No, fox fur is too coarse. You need grey squirrel for that ;-)
I can supply the pelts for 99p ea. or £10.99 plus p+p if you want the pleasure of despatching and skinning them yourself (in which case I will need a signed affidavit that you will not release them).
As far as bluetack is concerned - it's probably more expensive than claybar and won't give you any indication of how contaminated it is. With a regular claybar you can see the grunge it is removing and decide when to throw it away.
i'll have to take your word for its effectiveness as clay because im not dismantling my blu tack castle thats sat on my desk took me a week to make (its complete with map pin guards on the ramparts......it was a slow week )
