BMW X3 Service & Repair Manual: Notes on using temperature-controlled infra-red radiators
When using temperature-controlled infrared radiators, damage to adhesive bonds, paint and vehicle components can occur when drying spatula and filler.
The temperature sensors in the infrared radiator only operate reliably on large, even surfaces.
On small surfaces such as C-pillars or sills, often only a colder, adjacent area is measured.
This leads to actual surface temperatures of up to 130ºC, even if only 70ºC is set on the infrared radiator.
When the rear side walls are partially replaced by bonding and riveting, these high temperatures can lead to a visible pattern in the area of the joint.
Remedy: Check the surface temperatures on small component surfaces during the drying process with an external temperature sensor.
The general rule is: The surface temperatures must not exceed 85ºC.
IMPORTANT: Do not use infrared radiators on carbon parts! Risk of component destruction.
