Painting galv

Hi folks, not posted in a long while, my 90 has been off the road for at least a couple of years (been used in the fields though so still running good)
Its time for the long awaited rebuild, have galv chassis which will stay as is, picking up galv bulkhead soon.
My question is how to use t wash on the bulkhead before painting, do you use it neat out of the bottle or dilute it ? Any advice greatly appreciated.

I used a spray bottle (like a window cleaner bottle/something from under the kitchen sink). I sprayed it on neat wait for it to turn black then washed it off with water

T-wash (also known as Mordant solution) is just copper sulphate and is already a dilution. When I have used it I degrease everything, paint it on neat with a brush and allow to dry and then wash everything down with a hose and water. It is very quick to work so you will see the galv turn dull and black as you are painting it on. It is very simple to use.

Now look at the changing valve stem oil seals thread.
It's all there!

Epoxy primer can go direct to fresh zinc.

I'm not sure if I'd mordant wash or not. I guess I probably would.

(I paint alluminium for work with epoxy)

Hi Folks, thanks for all the replies, once again this great community comes up with the results ! Neat it is then, spray bottle sounds good idea, getting bulkhead tomorrow so busy days.......

I deceased my chassis and rubbed down with course abrasive pad, then used Buzzweld "Galve in One" , so far so good. My thinking was I wanted to have a paint that would stick on galvanised steel jus in case I missed a bit.

My chassis was certainly DECEASED

I used patio cleaner in a spray bottle. left it on about an hour then washed it off, painted chassis in black silk paint and it's still going strong years later. cheapest way to do it
