“Rain is getting in to my BMW, through my soft top, WHAT can I do to stop it?”

Hi Kev,

Unless there is actual damage to your soft top, such as a tear, then the best thing for you to do is apply Renovo’s Ultra Proofer; this will cocoon your soft top in a weather proofing coating.

However, because all of our products are in fact water based, it is very important that you ensure you clean your top thoroughly with the Fabric Soft Top Cleaner, before applying the Ultra Proofer, this is because if there are any patches of proofing agents on the top, then the Ultra Proofer will not be able to absorb into your fibres.

You can test for yourself that all proofing agents have been removed by simply sprinkling little droplets of water onto your soft top. If they start to bead like the picture above, then you will need to clean the soft top again. If the water absorbs into the fabric, then you are safe to apply the Ultra Proofer

The product is simple to apply, just paint it on and as soon as the Ultra Proofer is dry your soft top is protected. With additional benefits of mould, mildew and UV inhibitors in its formulation you can be sure that the fabric is well protected. Two coats may be needed, if you try to apply a second coat and it is not needed the Ultra Proofer will simply run off as it will be repelled by already applied and dried the first coat.


I hope this helps! Please do not hesitate to contact us if you have any further questions!
