paint question

[zimmy]

i just put a top coat of
eurethane on my hood and
even though everything feels
real smooth before i put it
on, i still getting a very slight
textured sorta wavey look to the
paint........
is this normal or should the top
coat come out looking like glass?
this IS the first coat...
will it smooth out after a couple more?
.........zimmmmy

if its not smooth the first coat, I don't think any other coats will be any smoother.

ive set and reset the gun!,
what if i just dump it on,
swirl, then drain!......jk
i WAS sort one part reducer on
that coat....im assuming it
would just dry slower....
fixed the next batch ,,,,z

It takes time, but if you want a really nice finish wet sand it smooth, probably 400 grit or so, before the next coat, as stated it won't smooth down if you are not painting over a smooth base.

A glass smooth surface is hard to get straight from the gun at least for me, but a light sand then polish can do wonders, but of course be very very careful on the edges and even curved surfaces.

If you are going to wet sand the final top coat and then polish you need to go with an even higher (finer grit) like 1200 or 1600 followed by a polishing with a good commercial polishing compound (I like Meguires or Dupont, the stuff you get at the paint store, not the stuff you get at the car parts store)

Miss Agatha was sanded with 2000 and 3000 grit then polished.

Orange peel. It’s completely normal for glossy paint. Severe orange peel is generally the result of incorrect spraygun setup/paint mixing.

Proper setup can usually reduce it acceptable levels, But it’s generally impossible to eliminated it completely during application.

As the others said, to get an ultra-smooth finish you have to remove it by sanding it flat.

A normal process for a clear topcoat would be to sand out the texture (orange peel) with #1200 to #1500 paper, remove that sanding scratch by sanding with #2000 or finer and then buffing with a rotary polisher and cutting compound. For a very high end finish you can sand with much finer abrasives, like #3000 or #4000 before buffing


PC.
