Pimp my ride
Was watching a pimp my ride episode the other day, they used foam on a roll then sprayed it with a gel coat, then reinforced the back with
fibreglass.
I think they were making a speaker pod but it filled the whole of the boot.
Has anyone else seen this process? Could you make a dash the same way?

I have used this process to make a moulded front for my subs that where in the boot of my escort. Some years ag. i stretched some speaker grill
material over a bendy mdf former to give it the desired shape then painted fibreglass resin over the top once it is hard fibreglass can be layed up on
the inside or out depending on what you can get to In your case the inside for a dash. worked well for me but the kind of shapes you can get are a bit
limited to how the material stretched around your former eg convex shapes are hard to make but yes the basic idea is good just have to have a play
about otherwise you could try making a foam former then covering in fibreglass then melting the foam former away with petrol then laying up a bit
more on the inside then a good sand and fill on the outside. Or a combination of the 2 could work well ?

Personally I'd make a buck and do it properly (it'll be the lightest option)....
Get some polystyrene, carve it to shape, slather it in filler, sand it all smooth, spray it etc etc etc etc....
It'll take a bit longer but it'll be lighter and look better...

The only problem with doing the carved foam / petrol jobby is its very difficult to make the surface very smooth. I did this to make my air intake and
its pretty damn good but there's still air bubbles, slight ridges etc. Vacuum bagging it with pre-preg would have worked better but my wallet
couldn't stand the pain  Admittidly on my plenum it was nothing a few tins of ali body filler and some elbow grease couldn't sort out...

pink foam, B&Q , carve with knife and then glass paper, I brush on white pva glue to seal the pores. Use either thin foam and vinyl or take a
glass mould from it.

Do you know which B&Qs stock this foam? Is it the megatron massive warehouse versions only or would the standard ones sell it too?
I can't find what it is on the B&Q website T_T

well I wouldn't call our Aberdeen branch that big, it's with all the house insulation in packs of 5 I think, about 2in by 1m x 50cm but
you can get different sizes elsewhere. I use the stuff to build r/c planes and boats, glue with epoxy.
I use a rasp to shape it roughly or even an angle grinder with a flapper wheel (big models, wear a mask!), I found glass paper gives the cleanest cut
for finishing.
