DEW Engineering?

[Pete Z]

I finally made my way to Ottawa this past week-end to pick up my M3A1 CDN2 and I have been going through some of the documentation I recieved with it. There is an old appraisal where reference made to the fact that both sides show evidence of recieving the "DEW Engineering patch kit" which apparently "was applied to the whole fleet circa 1981". Can anybody elaborate with details of what this kit or procedure consisted of? The truck shows evidence of some CF-performed body work with fibreglass repairs to the rear corners, front floorpans and rockers being fairly evident.
