Endlinks wore down paint on chassis, what's the fix?

[warhawk03]

I installed some Whiteline Endlinks along with a Whiteline Front Sway Bar. Before my alignment, the endlinks made some contact on the inner firewall/chassis and wore the material down to bare metal. I'd like to clean it up. What did Subaru use to coat the chassis inside the wheel well?

It’s just standard automotive undercoating.

I just use primer from a spray can. They sell undercoat in cans too.


I tend to spray it into paper bowl or something and brush it on because I prefer not to overspray everything in the vicinity.

Metal prep like rust converter then rust paint or something thick.

Primer in it self is porous, would definitely be spraying something on-top to seal it.

If it's worn down to the metal and not rusting, usually just touch up paint works. If it's surface rusted, sand it down to bare metal, possibly use some rust converter/prep, then paint.

If you're really OCD about it like me, do the touch up and Fluid Film everything. As in the entire car, even if it's a spring/summer/fall only car. I had the same thing happen and because it had Fluid Film all around it, it coated it without me even knowing after it happened and prevented any rust from forming.

Not too worried, as long as it's not polyester-based primer
