Being a New-England based company we see all variations of weather conditions. And we've seen more than a lot of seized coil overs and other metal items that have fallen prey to corrosion and rust. This Winzer Tek Wax is the best defense against corrosion that we have yet to come across. TekWax is a heavy-duty, flexible wax that you spray onto metal surfaces and it forms a durable protective film. It was originally used as a sealant for wheel wells, bodyshells, rocker panels, and chassis panels which makes it ideal for un-coated and exposed metal parts on your car. It has a high-quality matte amber finish that is also slightly tacky to the touch. Another plus is that it can give some components an original OEM appearance. We spray Tech Wax on our coilover threads to keep salt and sand from gumming up the threads and seizing the adjustment collars. We also use it on other exposed metal surfaces that don't have any corrosion protection from their manufacturers (steering hose fittings, even fastners and hardware). The finished surface has an amber (gold-ish) hue that blends in with many other hard parts on the car and it has an overall 'finished' look. TekWax is sold as a 24oz aerosol can. It ships by UPS Ground only. Follow instructions on the can for the best and safest results.

This Fire Wall Block Off Plate is the perfect solution for sealing off the engine bay from the cab in gutted track cars. It is pre-curved and has a bead roll to help retain its shape and keep out engine pollutants and other dangerous conditions. This plate mounts to factory locations and takes only minutes to install, needing no drilling, tapping, or welding. 

Fits both left and right side drive vehicles.

Use of silicone during installation can help create a tighter seal. Also, heat-reflective material can be used to help reduce heatsoak in the cabin.
