This is my install of Nathan K5HL on my 2007 F-150 screw.
I will be purchasing a turn key kit from realtrainhorns.net | Real Train Horns
, I have already talked to the guys there and they helped me decide on a kit.
I will be installing a 8 1/2 gal air tank and two compressors, and I am planning on everything being installed under the truck. The K5s and air tank will be mounted where the spare tire goes and the two compressors will me mounted under the bead just in front of the rear axle on a bed cross member.
Tonight I got the horns ready to paint by taking them apart and masking off the manifold where the horns mount up, and I covered the Nathan serial number tag. I used Dupli-color Acetone to prep the surface and remove the dirt/ oil/ ect.
Taped all 5 horn mounting locations, the mounting plate, the serial number tag, and the allen head screws
Self etching primer, Acetone, and painters tape( tip: get the 1 1/2" tape and the 1/2" tape, and a X-ACTO knife)
Do notremove the rubber gasket on the horn, just tape over it, just be sure not to remove it with the tape later.
It was easier for me to tape the outside edge with small pieces, use a knife to remove the over hang then tape the center
Here is everything prepped, masked and ready for the self etching primer.
I then used 2 cans of the primer to apply about 3 solid coats of primer to all pieces.
