Hello Is it ok to wrap the bonnet with a transparent vinyl before starting the moulding?  In order not to damage the bonnet paint. 
thanks

It is fine as long as you are using PVA release agent. Otherwise the gelcoat will attack the vinyl.

I am a bodykit manufacturer in HongKong. According to my 6 years experience on Hood molding. It was impossbile not to not
damage the bonnet paint for no matter what protections that you do!  Its just maybe damaged minor only!

I think you need to be looking at what is going wrong then... Certainly plug damage is always possible, but it is far from impossible to avoid it.

Hello

Pleas don't. When you making molding. You will apply gel coat. Resin. Those material will give out heat in chemical reaction with heat. Those will make the vinyl holograms on yr hood. You need repaint yr hood! 3d scannng yr hood is recommended for yr.case!

Like above, tried it before and the gelcoat weakened the vinyl making it soft and giving it some wrinkles...the curing of a mould can go up in temperatures till 70°C if thick lay up so this will soften the vinyl and glue as well... 
Like Hanaldo said above a PVA might make a barrierfilm to prevent the gelcoat softening the vinyl but heat will still be an issue...not saying it is impossible but take great care...I would personally rather go for the chemical release agent or pva straight on the hood and worst case you'll have to repaint the hood Smile
