Does this Chip & thin dent require sanding before touchup ?
 

The thin dent circled in red is less than 1mm deep and the chip is 2mm in diameter.

I would not sand. IMO, just get the touch up paint, fill it in w/ paint then use Langka Blob remover to finish flush with the rest of the body.

Should I use the langka blob after or before the finishing clear coat ?

Dab of touch up paint and call it a day.

So just the touch up paint is enough to fill up the light dent nicely ?

Also can I just use clear coat to fix the dent up or do I need the base + pearl ?

For pearl white paint (which is a pain), add a layer of base paint, let it dry, add a layer of base paint, let it dry (over and over again until it's about the same height with the body), and then apply ONE coat of the pearl. If you add multiple layers of the pearl, it becomes dark.

I would sand it a bit just in case unless you are sure there isn't any rust build up… Glue some sand paper on the tip of a pencil where the eraser is, and just give it a few rubs only on the metal. I've had similar chips in my fender wells.

Haven't tried but, what should I do if I see rust after rubbing down a bit ?

I've been using a blob of vase line to keep moisture out lol I don't know if it works though.

Yeah, so just clean out the chip w/ soap or rubbing alcohol then apply the touch up paint then use langka blob remover. No need for clear coat, just use base + pearl. It won't match 100% but it'll sit flush with the car and no one but you will ever will notice.

If it's not peeling, I would not wet sand. I'd clean with rubbing alcohol, touch up, then wax. Put 2-3 coats of wax on that panel/side...etc Don't do 3 waxes in one day, leave like 4 days in between for that spot if it's deep.

...or long way, bondo? It's just a precaution i'd take so it won't rust in future.


I'm overdoing it, ain't I?

Sand it first, reason being, you could miss any startup of rust or trap dirt in it.

when you say pearl, is it the crystal white pearl? like the color they have for the 2015 white brz's?
