Bonnet Mesh

How about a thin bead of Sikaflex - it's a cross between silicone sealant and glue.  Available from DIY shops or boat chandlers.

I used fiber glass resin it ran through the fine mesh and bonded well

also as nick said sikaflex is fine but takes a good 24hours to set as the resin takes only 5 or so more time for a scud in the sun

I had my grille secured with general clear silicone. It gave out after about 15000 miles. I've re-attached it with Sikaflex.

The reason to not use general "bathroom" type silicon is because the anti fungus additive may be corrosive to some metals. I'm pretty sure it shouldn't be near any aluminium, but I'm not sure how, or if, it would affect gel coat, or whatever the mesh is made from. I'm guessing that as many bathrooms have stainless and chrome fittings, it'll be OK to use with those materials.......

I wouldn't put anything "anti fungus" near that car Blatman

I didn't like the sound of the sikoflex stuff that people rave about (seemed really messy) so I opted for solid glue.

I used a loctite solid-glue-stick heat gun (needs a lot of sticks to go around all the sides of the mesh! ) for the two triangular cutouts in the bonnet, the V8 scoop and the exit from the ducted nose portion of the nosecone.

I was a little worried (still am to a degree) about excessive heat - mainly on the left triangular mesh where the exhaust manifold sits directly below, thereby radiating heat directly onto the mesh! I have got some silver reflective metalic tape which I intend putting over the glue to reflect the majority the radiant heat back into the engine bay. The glue seems to be good for just under 170 C (warning on the box about gun nozzle being hot).

I was originally intending aralditing some cable tie saddles onto the fibre glass and then using cable ties to hold the mesh in place - the main problem was the cable tie saddles where too thick so the mesh ended up being a little proud of the fibreglass surface.

Don't even think about araditing the mesh unless you want to just use say 4 or 6 spots of glue to keep it in place. You'd end up paying a fortune in aradite otherwise!

I am pleased with the results at the moment and hopefully I won't have any probs with the "mesh dripping off" the fibreglass!

Is this still the best way? Find the mesh is too fine so any silicon/gun stuff just sits on top of the mesh and doesnt bond. Read about resin options too. Got 3 bits of mesh to put in the new bonnet. All cut to (over) size but cant think of the best way to bond it all on.
