Fibreglass and other advice needed

[tikki169]

true gel coat can be brushed on but i dont like sanding for hours to get the brush marks out

That's why I was saying use sandable GC. It's alot softer and easier to sand but still has the strength of normal GC. This is what they use in alot of boat hull repairs and the stuff can be buffed up to a high finish.

Have a look for a a place like fiber glass international, here in Brisbane they are pretty well equiped with all your needs.

Agreed Du pont are the shit, they make the best stuff but you'll pay for it. Sikkens or Standox are also up there with the best and are alot cheaper.

Just outta interest would it be hard to make a mould of your own bonnet if you've never used fibre before?

[SirSkyline]

yep sure would becuase the the mould would have to be perfect. Then making the mould would be another story

I've been told by a fibreglass manufacturer that gelcoat is NOT what I need to use on the top, because its out of the mould. They've told me that Flow Coat is what I need to use, and its basically the same price, but slightly different in the way it dries. He says it will fill out the dips, and give me a good base for painting.

Re-enforcement has been arranged, I know how I'm going to do that, and I've sourced 450gsm csm for under 10 bucks a square meter. Not decided on what I'll do with the top. However, re fibreglassing the bottom may solve some of the hassles I have with the top of it. I'll be able to assess it more when thats done.

Thanks, Jase

Trust me mate do the top with poly and then prime it, it will look sweet as, like new

flow coat/ high build same same just don't brush it on

I've sourced some really low cost fibreglass and resin, gelcoat and all other associated bits. I'm wondering if I can put the money into a mould and new bonnet, rather than into fixing mine. If it was a straight bonnet, there would be no question about it. However as I want a vented bonnet, my only query about making a new mould, is how do i actually make the shape of the vent and put it on the surface of my bonnet so that I can actually create the mould?

Obviously the surface of whatever i use needs to be perfect, or at least something that I can make perfect once complete, before the mould is made.

Any ideas on this??

it can be done but every mould that is made allways has imperfections and require corrective rebuilding. it's probably simpler to fix what you have than to go through the stress of building a mould and frame. sorry i hate sounding negitive

im use to bulding boats and boat moulds
