How to finish this jockey seat?

Lads I've made a double jockey seat and just finished fibreglassing it, what do I put over the fibreglass to get the smooth finish?

My other double jockey has been painted with international toplac paint as it had gone shabby and I plan on painting this one the same colour when I get the smooth finish.

Flowcoat would be my first choice.

Top coat could be flow coat under another name, or could just be paint. Flowcoat is gel coat with wax added that means it cures in air. Gel coat doesn't cure in air. Its designed to cure when air is excluded and to be sticky when in air.

There are two ways to make a fibreglass box. The first is to use a mould - you cover the mould with gel coat mixed with catalyst. The gel goes sticky but on the mould surface goes hard as there is no air on the surface. You then apply chopped strand mat (CSM) to the gel which sticks because its sticky and wet it through with resin (with catalyst). Resin hardens in giving a hard surface. That works well for reproducing multiple of the same object.

Other way, for one offs, is to (as it appears you have) create a box out of say ply wood, cover in CSM with resin and catalyst. If you cover that with gelcoat the surface at the CSM will cure but the top layer will be sticky as its in air. So flow coat is the same substance but contains wax which floats to the surface once applied and creates an invisible air barrier causing the gel to cure.

Is that the actual seat? Looks like it needs a lot of finishing and fairing to make smooth if it is. What's it made of? Or over?

I'm no expert but I would get some shiny Formica laminate cut to the size of each side then polish with wax brush a couple coats of gel coat on to the laminate stick it to the sides then when cured take away the laminate and you should have a good face you can then tidy up the corners unless any one knows an easier way to make it good quickly

It's either that or start again. Buy an Argos mirror and lay up on the mirror. Gelcoat layers, then fibreglass. And like you say once you have four panels, join up and make the corners good

Or just go on ebay & type jockey seat pod loads available for just over 100 by the time you've bought all the gear to make one you could have bought one for the same money
