When you want to weld something, clean it thoroughly on both sides.. (in one of the last pics i see you did not clean the blue part..)  It's not just that you can weld it much better, the fumes are toxic and you only have one set of lungs .. Never inhale those fumes of welding, aluminum is even (much) worse than stealwelding.. you really need a extractor hood.

I often blow some compressed air over a weld when it's cooled down a bit, ( get some "clean" air at your workplace)  always good to have the compr. air at hand... when something gets on fire you simply blow it out. Also always a fire-extinguisher at hand is standard. (at least a bucket of water.) 

And don't do it like this guy, welding near or under flammable stuff...

WOW !!

This week I removed the sound deadening/tar mat from the car as preparation for blasting. To be honest I was really dreading this job but in the end it was actually not that bad! 

I ordered 5kg of dry ice for the occasion.

This worked an absolute charm for the boot area. Leave the ice on the matting for a couple of minutes and you can start to hear it cracking. Then use a scraper and it comes off in big slabs.

the transmission tunnel area is much more difficult, dry ice can be used on the top flat surfaces but doesn’t work on the sides, I tried hanging plastic bags with dry ice in them but it just doesn’t get as cold…

for the sides of the transmission tunnel a heat gun and scraper worked great for me, trick was to get it hot enough to lift off the metal but not so hot that it melts completely.

and end results…

still finishing up the bracing, only managed to add a cross brace for the rear of the car as I’m going to remove the entire rear valance.

Good presentation. Thanks.  A few questions:

  • What was the cost of the dry ice?  You would have paid in Australian $, of course.
  • How was it packaged for transport?
  • How did you handle it when working with it in the shop...  gloves?  garden trowel? 
  • Was 5 kg enough?

It was $50 Aussie for 5kg, it was just in a polystyrene cooler, and I used my welding gloves to handle it. 5kg was just enough to do all the flat surfaces
