Hi
Im replacing my head light covers next week and wonder who has bolted them into place rather than stuck them in?
If you bolted them what did you use riv-nuts or glue nuts in to bolt to.
Thanks
Dom..
Ours are rivnutted into place. Used M4's if I remember correctly. Only issues is that a lot of crap tends to get stuck behind them, but if you don't mind cleaning them out every so often it shouldn't be an issue.Im replacing my head light covers next week and wonder who has bolted them into place rather than stuck them in?

Bolted mine in and used one sided foam adhesive tape to keep the water out.
Rivnuts are the perfect solution as long as you add some sealant to the back of the threaded screw.
What size, type and material rivnuts did you use? Rivnuts are the perfect solution as long as you add some sealant to the back of the threaded screw.
Does the glass fiber hold the rivnuts or did you use epoxy aswell?
Dom,
See my post. My headlight covers are not bolted and are removable. One year now with no problem; however, I did notice that when it gets very hot the strip caulk can get soft. What's nice is the headlight covers are removable and great seal is provided without being glued. I am worried that if it is too hot on a track day the cover could come off if air keeps up under the bottom edge so I plan on adding at least two bolts/screws to make sure they are secure.
If you go this route, the 3M strip caulk come in thin strips. I outlined the perimeter with 3 strips side by side, water and dusk will not get in.

as you can see on the pic i did not use the black primer, since at stoneleigh all cars were showing signs of delamination. I have made some tests with black primer and could not find any that is sticking to the perspex (transparent plastic) in a way I could be satisfied. So in the end I did not do it at all and am quite happy.
I made one last test with black expoxy and that is ok in terms of sticking, you will get it from special shops !
I did not use any sealing cause sooner or later it will look dirty or get yellowish from the sun. Water can enter and also exit and it is not a bad idea to vent this area anyway.
Once in a year I remove the 2 screws and clean the inside and the plastic and I can only recommend going that route !

What there peels off is not the adhesive itself, but the UV protective coating on the polycarbonate which dissolves from the surface because it can't withstand tensile load by flex and tension.So when the cover is not glued in, this should not happen.
I need to replace mine and will attach them also with screws (like you did).

That looks very neat, Spatz. Is that just a pair of M5 screws tapped into the GRP or did you rivnut?I made one last test with black expoxy and that is ok in terms of sticking, you will get it from special shops !
