Hey Guys,

I just finished applying two coats of clear to my freshly painted hood.

Two things:

Firstly, there are some specks of dust that I did not wet-sand before applying the clear. Will wet-sanding the clear be sufficient to hide the little bumps that the dust created?

Secondly, it was my first paint job with real paint guns. I was pretty generous with the base coat in order to hide any minor imperfections that I missed. It turned out great! So, I decided to apply the same amount of clear. At first, everything looked perfect, but after a while I noticed a few runs developing. Will I have to re-spray the clear coat after sanding down the runs?

I plan to wait 48 hours before sanding the paint. It’s very warm here (above 25c) so everything is drying quite fast.

Any tips for making wet sanding more effective?

Thanks!

If the specks of dust and such are within the pigmented coat then wet sanding the clear most likely won't do anything to remedy those specks, the claer may enhance or hide them though...it's a crap shoot.

As for runs, just pull back a pit on the gun to help avoid those. To remove them we usually use a sanding block so at to isolate just the area needed to be sanded. 2500 to 3000 is ideal unless it's a huge sag.

Most final sanding you'll want 2000 grit and up as the sanding marks will be easier to remove. Soaks your papers for at least 30 minutes in warm soapy water prior to sanding, keep the area wet and check your work often. Use a sanding block instead of your fingers alone or you'll get an uneven sanded surface. Also make sure you sand always in one direction.

Good luck,
Anthony

Hi Anthony,

Thanks for the reply. The specks of dust landed on the pigmented coat.

I will have to be satisfied with whatever the results are after wet sanding. Having said that, it looks a lot better than before! Actually, the rest of the car looks downright tired compared to the hood. Maybe a good compound/wax/polish job will help it.

How long should I wait until I can sand the paint? It has been three days since I painted it.

Thanks again!!

It can be sanded now....it could of been sanded shortly after being painted when is usually the preferred time to do so as the paint is soft and responds well to sanding and polishing.

Make sure you block sand it....you'll want to sand until most of the gloss is gone from the surface then begin your polishing process, be extra cautious near edges.

Wow, what a difference! Excellent!! Hard to tell, but it looks like there is no orange peel going on, right?

The DareDevil

Hardly any. That's what I liked about the guns: the clear went on silky smooth!
