|
|
Hi,
First attempt at changing a tube in a barco lc chamber. I followed the methods in the advanced procedures. The only catch is with my putty knife I cut into the aluminum a little bit on the inside of the chamber.
Is this an issue?
Does it need to be painted?
Will this cause "fungus" ?

Ethylene glycol corrode aluminium (-> fungus), that's why it's needed to use polyethylene glycol for cars with aluminium motor block.
I use polyethylene glycol mixed with glyserine (70/30) in my LC chambers, other reason was that I couldn't get non colored ethylene glycol anywhere.
You can fix that coating with same rtv what you are using to glue tube to housing.

Good to know I will cover up the cuts. I read on here that GE silicone II 100% black is the stuff to use
