Hello

I've been lurking on here for a bit now, watching the videos and soaking up all the info I can. I think I'm at the point where I've learnt as much as I can and it's time to get my hands dirty.

My first project is to create a carbon panel to replace the air bag on the Momo sterring wheel from my Accord Type R.

I want to take a mould of the plastic cover that the airbag bursts through when things go wrong.  This cover has a leather effect grain, which I would like to fill and smooth before I take the mould.

Can I use regular high build filler primer from a Halfords rattle can ? My plan is to spray a few good coats over the whole part and then wet sand it smooth. Would this provide a suiatble surface for tooling gel ? Or would I need to seal it up with something else first ?

I hope I've explained myself properly
