Heat stripped a 911 chassis
After wire wheeling and heat gun cleaning paint and goo off tubs as I went while installing tubing or making repairs in the past I wanted to try the easy way out on this one. Started with a 77 911 with no dings and almost no rust and it came out looking like a NOS part. Not a spec of anything left anywhere. Cooked and washed out from ever nook and seam with no dust, shells or grit anywhere. The lead melted out too, ready for light weight filler now. You can see the original dip lines from when the tub was galvanized by Porsche. Not cheap but I will never again strip a car any other way. Sheet metal is smooth with no distortion of any kind. They heat to about 700 in a no OX oven, cool and pressure wash the ash off, give it weak acid dip and pressure wash again then wash down with a phosphate rinse. No disturbance to existing galvanizing or metal.
The TIG welder sprayed some coolant when it saw the project roll in the shop.

That is really nice Kurt. Definitely agree about it being the best way to go. Hope that you're planning on putting something a little stronger than a 912 motor into it! BTW, where did you get it done?

Can you talk more about the heat stripping process. When I built my racecar, I had it acid dipped which is a process where the chassis is baked at 600 degrees to turn paint, seam sealer, undercoating, etc. to ash and then dipped in acid to clean the chassis. It looks just like your and I'm wondering the details of your process.

That looks marvelous!
How hot is the process? Is the zinc coating still present afterwards?
Thanks for sharing!!

Great looking job!
I wish my car looked that good with paint.
