This stuff goes on very easy and lasts long.

Parfait pour toit décapotable.

I saw this recommended in Auto Express and gave it a try on my MX-5. Easy to apply and incredibly effective - water just beads up on the roof and lasts for up to a year when garaged at least. Just make sure you cover the windscreen before applying, I didn’t first time and caused awful smearing in rain (think RainX if you ever had the misfortune of trying that!) and ended up changing the wipers. Otherwise fantastic.

This is a great fabric protection product. While costly, I think it's worth it as it doesn't stain or discolor, leave a residue I can feel, or an odour. It is smelly during application, but that fades within a few hours as I aired out the car. Watch online detailing tutorials to see how best to apply this product.

Works well when applied in multiple coats. It says a single coat will do - and it does. but I recommend two coats for best results. 1) clean the fabric with a hoover and brush to remove all the debris 2) spray the item in even layers from a distance away from the material to allow even spread 3) repeat step 2 when the first coat has dried. Thats how I get good results. The longevity and durability is pretty good. There is a fairly bad scent when spraying but once dried it is absolutely fine.
