gel coat it before you lay the glass!

Gelcoat is only used in moulding, as the resin contains no wax to cure the surface. The surface (exposed to atmosphere) will remain green to allow subsequent layers of resin and glass mat to adhere to the gelcoat. Flowcoat is used as a topcoat (allowing pigments to be added for colouring) and contains wax in the resin to seal the surface.

Be cheaper and easier to buy a commercially made glass bonnet. They have the moulds and the chopper guns to make them fast and cheaper.

Use a fibreglass primer first, then go in with anything else.

IF YOU HAVE SANDED THE ROOF BACK, MOST FIBREGLASS ROOFS ARE MADE OF POLYESTER OR VINYLESTER RESINS. AN EPOXY UNDERCOAT WILL ENSURE EXCELLENT BONDING TO MOST SURFACES. THEN THE CHOICE OF PAINT IS UP TO YOU. FOR A TUFF FINISH MAYBE AN ENAMEL. EASY TO USE AND VERY LITTLE ORANGE PEAL FINISH. IF YOU WANT THE EXTRA WORK A POLYURATHENE WILL GIVE YOU A BETTER FINISH.
GOOD LUCK

If the surface is already gelcoated all you have to do is what was first explaned ,just lightly sand the gelcoated surface then piant it!
If the surface is not gelcoated sand the surface (120grit) then prime the surface with primer suited to what paint you are using then go for your life .

You dont have to gelcoat the mould first just depends on what finish you are after but it is recomended.
If your are after a glass bonnet get in touch with JOE BRADLEY at Brendale he did have a complete set of moulds for a cruiser.

1.Gelcoat is not necessarily used for moulding.
2.There are resins that contian wax and can also be used for laying up.
3.If the product remains green you have some serious problems as it would be under cured and 90% of your inground pools and boats would be STUFFED as unwaxed resins do not remain green if they are not flowcoated.
4.Flow coat is only gelcoat with 5% of wax and styrene added(left over gelcoat)
Im at LOGANHOLME if you want me to have a look for you just pm me

I worked in fibreglass for 9 years making tangara train panels and Landrover bonnets and instrument panels for the army 6WD's and all we ever did was make them in injection moulded like most FRP roofed 4WD's in vinyl ester resin, then we sanded them and painted them with an etch primer prior to painting in a 2 pack enamel. The polyurethane is good, done alot of yachts and pools in it, but probably a little overkill for a horse float. An alternative would be to spray flow coat back on for a finish like it originally would have had.
anyone living in Newcastle area want FRP panels for a 40 series go to tech I and a couple of other cruiser owners made the moulds for the bonnet, guards, windsreen surround, tailgate, doors, radiator support panel and a roof console, in a previous life before I found Hilux.
