So whats a good fit for a Gunlogi rail tank and any tips for rail tanking and when to use which mod.

Damage mods, IMO, are only useful for smashing redljne tanks.
Using a nitros allows you to NOT get hit. It is more beneficial than a DMG mod.
It allows me the tactical flexibility to brawl with ion cannon madrugars and win.

My PC fit:
Gunlogi

80gj Particle Cannon

Complex shield hardener x 2
Complex Nitrous/Fuel Injector

120mm Plate
Complex Rail gun Expansion

I have yet to find a tank that can dominate me except psychotic shooter who is undeniably best blaster of all time and he only matches me.

I seem to have the fitting idea down, but what about module activation?

I've been running a sica with one hardener and one damage mod, using a standard railgun, and my lows are a armor hardener and a heavy armor repair.

My strategy so far is to be sneaky and when I find a tank, activate both mods and circle the tank doing my best to take them down. But in case things go bad I use my armor hardener to keep me alive as I'm running away. It seems to work good so far, but you say to go with two hardeners.

So when do you use them? Do you always keep one in reserve and run the other one as much as possible? So half the time when you run into a tank you're double hardened?

Hardeners for close range
Damage mods for long range.

Generally, for every 200m that you plan to engage an enemy, put on one damage mod.

Activate all hardeners at once if you have more than one. Retreat before they run out. Reengage only when fresh.
Activate at the last second possible. Its a good tactic to fire an single round at an enemy tank and force him to run gardeners. About 75% through his hardener duration, begin the engagement. Only activate once he has decided to return fire, but before he does fire; watch his turret. When your hardeners are dry, pretend they are not, when they are ready, act as if they are dry. Deception is the key to tank on tank combat. You want to know everything about them and them to know nothing about you.

Most tankers in specific builds will engage in one manner with it. Find the counter to it, and allow them to think it will give them victory; then exploit it- a rail tanker must feel he owns the battlefield if he will leave the redline. A nrawler must feel he can close the distance. A missile will believe he can out DPS you before you can to him. All of this must be understood so that even counters to your build put themselves in their weakest possible state so you may exploit it.

You sploded me today :/

I've been rage quitting a lot lately...getting frustrated with Dust in general. Constant lag. Rail gun not shooting most matches. Glitches RDVs. If I want to run infantry my team gets tank stomped.

Ugh...
