- This video covers how to heat shrink aluminium panels in order to remove high spots or reduce shape and stop 'oil canning'.
Tools required: gas torch and slapper
This method can be used on steel panels too - the steel can be heated to cherry red in order to get to the correct temperature.

Enjoyed that a lot. Only worked on my Landrover bodywork, not super critical but have enjoyed reducing dents and oil canning- not as easy with propane torch and can’t afford oxy/propane.
I work on slightly more ham & egg stuff and don't have ages to spend lifting dents - time is money, blah blah - but I still need to get shut of oil-canning & dents.. I grab a gas torch - just a basic Map gas torch - plus an airline, heat the area in decreasing circles quite quickly, then focus the heat on the center for 3-5 seconds. I then blast the center with the airline/blowgun - you can watch the metal contract & lift. Once you get the hang of it, it's the fastest & easiest way to get shut of oil-canning or dents. Dents no longer cost me a thought since I started doing them this way - you can remove even very deep ones in no time. Heat, airline, bish bash bosh - gone. Nice flat panels, no great need for filler. :-)
When you start doing it this way, dents will take ages till you get a feel for it - but once it "clicks" inside your head, it becomes a doddle. You start telling the metal what to do, not it telling you what it feels like doing. When you begin to realise that the airline - despite blowing - has now become a "metal sucking hoover", then you've got a real fast tool in your toolbox. It's real counter intuitive - how does an airline that is blowing out pressurized air suck the metal out instead?? But it does... Real predictably too.
Great tip, thanks. I'll definitely give it a try when I'm next working on dents.
That was art in the best possible way - impressive skills!
Thanks!
I'm going to have to try this. I started making the panels for my Riley Brooklands in aluminium and over cooked the first one. Got one spot I over stretched I think. I am out of practice and I never had that much practice to start with! It's good enough to start making the other panels and gas welding it together but then I will need to tweak the shape before permanently attaching it to the timber frame.
Can this same process be used on newer aluminum body cars and trucks?
Curious about your choice of surface finish. Thank you for sharing.
Thanks. I'm not too keen on shiny cars. Rat rods and oily rag are my thing!
thumbs up!
Nice skills! I never worked with alluminium before, but you make it look easy… I’m curious about the finish you’re gonna give it! Paint, polish or just a little bit of sanding and clearcoat?
Thanks! I was thinking of painting in red but I might leave it unpainted for a while. I'm going to give it a light sand so hammer marks and joins are still visible. Not sure if I'll clearcoat it - I have a bare aluminium bike which is untreated and still looks quite nice after 2 years.
@@GasoliniASMR Totally understandable!! I like red. But once you paint it, there will be no going back! I guess you already know the dangers of galvanic corrosion right? (Aluminium rivets installed by the previous owner of my lancia fulvia rusted all the steel around it…) but aluminium does also rust in it’s own way..
Good Morning!
At 4:30 you put the panel back on the wheel...that won't change the shape of the panel after you've worked so hard to make it fit?
Hi Dave. I put it through the english wheel with the wheels at about panel thickness of 1.5mm so that should just level and smooth the surface without adding any shape. Closing the wheels tighter than that would start to add shape.
What is the weight of the Etceterini compared to the other 2 seaters you have showed (Ginetta etc). Will it have a comparable power to weight ratio?
I'm hoping to beat the Ginetta for weight and get under 500kg. The Etceterini doesn't have much power, only 30-35bhp, but that's the way I like it!
@@GasoliniASMR Thanks for the reply, Looking forward to the next episode. Keep them coming...
