Fibreglass product making process?
Having read some really good info from CFS Fibreglass (http://www.cfsnet.co.uk/Web_FibreglassGuide.pdf) I'm just looking to get confirmation on
the process.
Say I have a dashboard, which I've made up from 5mm ply, 8mm foam and a top covering of some fabric, all dials/switches/dash are fitted and it
looks like
Is this the correct way to make a fibreglass version?
- Remove dash/switches/gauges
- Cover dash with some polyprop sheeting to protect it from gelcoat
- Apply release agent to the polyprop surface including the edges
- Apply gelcoat (Resin B) to give me a nice smooth surface of the mould (yip i'm doing a mould first)
- Apply a general purpose (Resin A) resin and 450g CSM to the gelcoat layer and build up 4-5 layers of thickness using a roller to remove air
bubbles.
- Add some wood strips if necessary for strength/ease of handling.
- On the edges I'm just going to leave eges dangling/dripping and possibly add some wood strips to strengthen.
- Leave to fully cure for 5-7 days, remove and air dry for a few hours then wash in warm soapy water.
- Hope the gelcoat is nice and smooth.
- Tidy up edges
- Apply PVA release agent to mould
- Mix some wax in with the resin B and some colour pigment.
- Apply resin A
- Apply resin B and 2-3 layers of 450gsm CSM to mould
- Wait a while for it to cure (how long?)
- Pry from mould
- Trim edges
- Cut out holes using original dash as a guide.
- Realise surface is too shiny for a dash and cover with foam/vinyl.
Note: In all places resin has been used, catalyst has been used too before mixing.
Any tips/corrections appreciated.
