Hi and welcome from me in north Oxfordshire.
Sorry to say that I can't help you out with that, as I never used any products on my soft top, as I had the hardtop on most of the time and when the soft top did get worn out I had a new one fitted.
Thanks Hard top for that. Will brush up on my Dutch and check it out! Did you have your new soft top supplied and fitted in Holland or in UK? Could you recommend anyone in particular?I have just done a search on the web and found this company here in the Netherlands.
I hope that this might be of some help :-
I had it done a long time ago here in Holland and the local company that I used is no longer active as the owner retired.Thanks Hard top for that. Will brush up on my Dutch and check it out!
