Massive hole....

I am just starting to refurbish my Tornado and there is a large hole in the side of the console which used to allow access to the fuel tank. How do I fill this so it is nice and strong and gives a good finish. I am painting the boat white anyway so colour is not a problem. I was thinking of flowcoating the inside of the aluminium plate, glassing up the inside, then removing the plate? Any experts out there want to give me some advice? Will the GRP adhere to the ally as I have no experience using wax or releasing agent?

Hi Jiz, Acetone is the standard prep for Resin. Be careful how you store as it has a flashpoint of 24deg as I recall. After that, Resin sticks to nearly everything except Silicone Oil WD40 etc.

However, depending on teh colour you paine, how about different idea.
You do not need huge reinforcing and its not a strategic fix,
Depending on the colour you paint,I would cut perspex sheet to size and bond using resin to Both sides using bevelled edges on Perspex (heavy duty).
You can use Carpenters cramps to Hold tight when bonding.

A cleaner way may be to use Stainless Steel and do same other side so it looks cool.
Other than that you can get a "Cable Coller" to fit hole from Any marine shop
You will see these here the control cables leave bulkhead to go to engine on "nicely finished boats" this is a water tight fit and the seal and spray/Paint alloy after either acid dipping in Galvenising plant (5 pound max if not for free)

Thats only my twopence worth, hope it helps. There will be thousands of ways of finishing but if its painted properly you will not see it.
You could also just acetone plate (get from Chemist) and fit coller or plastic plate in little hole, paint in resin for coat, then gel coat paint the lot.
You will not even see it.

Sorry, obviously I don't want it to stick to the ally plate, just use that to get a smooth finish, a bit like a partial mould?

Jiz, give the ally a coat of release wax and your method will work fine. I made 8x4 sheets of laminate by laying them up on an ally sheet. I only waxed it the first time, after that there was no need.

The only thing which occurs to me is the slight leakage down between the plate and the side of your consol. Rub a smear of plasticene into any wee gap that might be there.

Personally, I'd find a panel that fit into the hole reasonably closely, and patch that into place. Lot less glassing, I'd think.

trim the hole neat so you have good clean edges. then sand the inside so it tapers to nothing (or nearly) from about 10mm. use the ally (or melamine) but give a coat wax first. then screw it on from the outside with screws that are just long enough (or grind off excess). gelcoat the area from the inside on the temp mould. when gel has gone off, apply csm and resin using a larger piece for each layer. following day, unscrew temp mould, countersink screw holes and fill with gelcoat.

jobs a goodun

Nah, just use a wee polish of release wax.

No need. Endeavour's advice is spot on.

Eh? I'd have used a very different approach myself, beginning with a handful of spit.
