Under Bonnet Insulation
Discussion
Chaps, Ive been fighting with the under bonnet insulation for a number of years ... sticking the bits that start to sag down and scraping off the horrid glue that seems to get everywhere.
So I bit the bullet last year and removed mine completely in search of a suitable alternative.
Over the years, Ive seen ali foil stuck to the underside of the bonnet, and of course is the horrible matt you can buy for classic cars, which got me thinking ...
So Ive been playing with some insulation and layering it with the kind of fire resistant and retardant fabric you get in fire blankets
If I can get some prices on materials / work time etc to produce an under bonnet heat shield, say using modern heat reflective materials / with sound deadening materials bonded to it that offers superior fire and heat resistance as well as sound suppression but with considerable weight saving over the origional Butyle rubber item, would anyone be interested ?

I was thinking more of a copy of the original using dense flame retardant foam, laminated with fire proof/ heat reflective matting (fire blanket stuff). Works out about £40 to buy the materials and adhesives, then cut to shape and bond to the underside.
Not just a case of fireproofing, but also heat and sound insulating

Whatever you use you will find that unless you remove all the old glue and ideally back to the fiberglass anything you glue on will come away.
After several attempts on my bonnet blanket not Wedge and them coming off i had an old blanket sent it to Lee at Trim Unique and he made me a new one.
Then bonnet off and stripped right back to the fiberglass too ages but then applied with high temp Glue that Lee provided.
Putting two coats on the Blanket the second after 10 min as it soaks in quite a bit.
I did in sections from the top so doing 12 inches at a time
worked very Lee has since done a Wedge in the same way and looked very good
