Insulation
Well,
Since the insulation was in such poor condition when I bought the car over 4 years ago,
I removed all of it immediately. Don't remember a cut out for the fan, but nothing hits with the hood closed and engine running. Been raining here so I have not test driven it yet. Will do so today.
To hide the logo was a suggestion by m_thomson when I first inquired as to availability of OEM materials (search "fire wall") ...vinyl bumper coat paint. I used "Honda Black" and first tested this when I fabricated insulation for the upper fire wall using 1/2'' Dynaliner. Ran the car pretty hard and left the hood closed during cool down and no ill effects to the paint or the insulation. I will post later today if I find any problems after the test drive as to the bonnet using these materials.
To make the templates, I used heavy mil plastic and stuck it in place with black window caulk, a tar like substance that comes in a roll and quite handy for doing this kind of thing.Then trace your outline with a ball point pen, it nearly cuts through the plastic. Cut out the plastic shape and then glue to card board with a light coat of 3M super 77 adhesive. Cut out the cardboard to shape, test fit and fine tune then transfer to the Dynaliner material. This is a self-taught method but works for me! I used a straight edge and utility knife for the straight lines and cut the arcs by hand with a decent pair of scissors. Cleaned and prep'ed removing any loose material. Wipe surfaces first with paint thinner then again with alcohol...stove fuel at 99 percent. Job took 3 hours total for the work and 10 hours of contemplation...
