    Bonding glass scoop to steel hood?

    I want to fix a '60s style glass 'stinger' hood scoop to a steel hood. Trying to get the look that Baldwin Motion and other tuners got on the Camaro and Firebird hoods. I don't know a lot about fixing f-glass to metal...so first will this mod have a chance of lasting without developing cracks , also any tips for a strong bonding agent to keep the 2 materials from coming apart?

    Maybe technology has moved on but I've never seen one that hasn't cracked eventually. Different flex rates cause a problem.
    Last one I did was an early Mustang and I glassed on the scoop and had a mould taken from the finished item giving me a glass bonnet. Bit extreme financially these days!

    That's the reply I was afraid of Steve
    Seen some nice examples on American ebay but of course they may not last.
    It may be that custom moulded hoods exist in the States,but never seen them for sale...Thanks for the warning

    you can stick it together , but yes as said they do crack and it's hard to say when , ie~ that'll last years guv or i'd give a fortnight and sell it guv ..

    i've glassed fake scoop's on the lax power cars and they've held up ok ...

    if you've got both bit's we can mould you one up if your stuck /not happy with it

    no worries

    if it's a thick scoop, as in thickness of fi glass , you could always give it a bit more strength by counter sinking some rivets round the mounting area

    you know where we are if your stuck

    sms body filler , when my mate done my bros rear arches on his 100e (lengthened fibre glass arches ) he put in a couple of self tappers as a giude and then put the sms filler on both surfaces and bonded them together , that was four years ago and no cracking at all

    Or glass studs to the bottom of the scoop and bolt it on?
    Have a proper join then with possible piping on it. (like arch piping).

    as vin said my mate used sms filler[looks like very fine black fibre glass] he bonded the arch to the under side of the wing ,self tapered ad clamped to the rear quarter.when it went off he removed the two screws and g clamps and spread the sms filler on the outside.he repairs lotus`s and the likes for a living

    Problem on an American bonnet is that large expanse of wobbly metal!
