Best under car paint/protection process?

[Richy12]

Hi guys, what would be your preferred method of finishing the underneath of a nova. It is currently in etch primed from the media blasters.

Any advice, fire away?

I used etch, seam sealer, por15, 3m stonechip and 2k paint brushed on. It's been great for about 6 years of road track and gravel traps
