That’s why it’s best to use a nibbler or shears. No sparks. Still need to cover the van, but only below the window panel.It’s not all that bad to be honest! I had a mate help who has done it before so that have some confidence.
The big learning is to make sure you cover the rest of the van body to prevent the sparks settling on the paint! Had to do two wounds of decontamination to get them out of the paint the next day once the bond had fully cured! Pics to show the contamination levels!

Also, don’t forget to have a really good fish around with a strong magnet inside the panel crevices. Any bits will fall down into there between the inner and outer skins when you cut. I got absolutely loads out of all my panels using a magnet and then finishing off by scraping around with a magnetic screwdriver to get the last few bits.
