Hi Kuba, I haven't reinforced the floor with anything rigid, if you add enough layers of medium to heavy CSM then fibreglass is rigid and strong enough to work as a floor.

Having said that, I've now had time to go all over the floor banging it with the pointy end of a screwdriver and I've found that there are a few voids where the CSM hadn't bonded to the gelcoat and a couple of soft areas where the CSM wasn't fully wetted with the resin. I'm pretty sure that's down to the resin being too cold when I mixed it, it felt a lot thicker than usual and although it soaked into the first couple of layers of 200gsm mat, I really had to work it into the next couple of layers of 500gsm, which are the layers where it's soft in places.

So, the plan is to bring the resin indoors to warm up for a few hours then stiffen up and repair the voids in what I've done so far before painting, polishing and prepping it to use as a mould for the finished article.

When I use that mould I'll make sure that the resin is warm enough, that the mat is thoroughly wetted through and I'll also be adding in some core mat to make the floor as rigid and strong as possible.

Anyway, I need to get some more resin and catalyst ordered as I'm down to my last few kg's.

Oh, I do like that 'Porsche' steering wheel, btw. I'm not sure what it's from but it has the look of the early Spitfire/Herald/Vitesse wheel, so it could be an old Standard (Triumph) model. I doubt it would fit my steering column, but I do have a classic wood rim wheel with a Porsche crest already.
