paint problem mystery
 

I recently noticed two blemishes on the roof of my black H3. They are quite different and I don't know how long they've been there (well, at least <1year, the last time I washed it). Got any ideas the cause of them?

The first is near the front edge, passenger side and looks like the paint just disintegrated in a shotgun pattern; the surface is very smooth. I presume the grey showing is primer. Should I worry about this getting worse?

The second is on the same side as the first but about a foot back and looks like something rusted, but I don't know how anything metal could be stuck there long enough to rust. (I drive it daily.) You can see a similar thing next to it on the plastic trim.

Sorry for the blurry pictures. I can't get any camera to focus on something close up.

Linex the roof.

Why Line-X it vs repaint it? Just to make it forever durable? Are these kinds of problems common on H3 roofs?

It looks like the paint is really, really thin on this vehicle...

Looks like your H3 had a repaint to me.

My black roof had some hail damage and some paint crazing, to repair and repaint the roof was going to be a couple of thousand dollars+

I use roof racks in the winter to throw snowboards / skis on, so instead I had the roof and hood Linex'ed - was around $500 for the two.

Looks good, virtually impossible to damage, and hail will never be an issue again. Probably going to get the brush guard and runners done too.https://cimg8.ibsrv.net/gimg/www.hum...f38c5256e2.jpg

Looks good.

Looks bad ass!

Very nice!
