My opinion is simple: Keep away from silicone-based sprays and household polishes! That said, modern automotive paints are such that you can wax your bike as and when you like. In any case, the bike was manufactured some time ago and has been on the high seas and in various bonded warehouses for sometime
My advice is to protect your bike's paintwork by using high-end automotive products such as Meguiar's Car Care products. Here is their website: http://www.meguiars.com/international
In particular, even though it is expensive here in South Africa, I use Meguir's GOLD CLASS™ CARNAUBA PLUS LIQUID WAX
. After all, my bike deserves the best!!!
Just my two-cents worth!
