If it works Use It!
I prefer an etch in light grey, then a Primer on steel parts. The Wattle range has very good rust prevention properties and covers well.
Red oxide for me is to dark and requires more top coat to cover.
I also only use an etch on alloy as most parts are rough cast and require less adhesion for top coats.
With all this said, traditional red oxide was generally of a higher viscosity and covered imperfections well, in addition to its rust prevention properties.
3 coats would give a very stable base and good fill without having to use a high fill or putty.
The other small negative for me is chips/ scratches....the red sticks out like a sore thumb.
All in all its still a good choice, easy to use and definately prevents rust forming and penetrating a nice top coat.
And if its worked for you in the past, then DONT CHANGE A THING!
Looks great and I can't wait to see more of the Triplets!
Nice to see you back on board Polybus
