High Temp Metal Filler??

[fly fisher]

Hi,
Can anyone recomend a high temp metal filler that could be used on an engine bay pannel (non structural). I want to repair a corrosion area, its not accessable to weld in new metal and due to it being 'non structural' was thinking a high temp filler..

Thanks,
Will

You only need normal polyester filler in an engine bay.
