I relearned how important it is to cover up glass when welding on your car or truck. I finished up fabricating a kayak rack on my old Toyota truck this weekend and while I wasn't worried about hurting what's left of the paint, the window glass did take a few hits from the mig splatter. Not that 914's ever need any welding, right.... So cover up before you get started and save your windows.

Them sparks ain't harmless.
COVER YOUR GLASS !
Sandblasting ? Even Worse !
Ruined.... RUINED every piece of class in a 356 .
Protect it before doing either welding or sandblasting.

The same goes for grinding sparks
