I've used the Gliptone all over my seats. Not had any problems.

 

looks like the carplan stuff wasnt the best buy then
i did intend to get meguiers, but they were re-vamping the store so didnt have asmuch stock as normal.

so far i've done a fairly thin coat of liquid and not much difference... other than it looks more matted and grips more. i'll give it more coats untill it doesnt absorb anymore and see what it's like then...

 

Meguiars for me!! the leather restorer and conditioner really works wonders on lifting the daily grime out of the leather, then leaves a beautiful lustre behind!!

 

+ 1 for Zymol. That stuff smells heavenly - and I swear it puts the spring back into the leather......

Use it on everything leathery and plasticy - just don't get it on the bottom of the windscreen - that stuff smears for days!!
