First time I've used it....can't get the paint to come through

call dealer or a body shop for paint code crossreference

You have not mentioned what kind of paint you have used, however, here are a few ideas.
We might accidentally hit on the one.
Some paints, such as latex or enamel, can do this if the first coat of paint is not completely "cured" before you add the second coat.
To be completely "cured", paint has to dry and harden for a set amount of time.
You also did not mention your location, but temperature & humidity can affect the drying time as well.
If the weather or the room is cold and/or damp, that can keep the paint from drying.
The colder and the damper, some paint will not "cure" at all!
If you used an automotive paint, properly mixed paint sometimes has "dryers" added to the paint to help it dry, but the same applies about the temperature and the humidity.
Automotive paint that is meant to be sprayed on cannot be brushed on, for the same reasons, it may not dry.
God bless your efforts.

Our firm supplied Ford the paint durability technology that was used at the Ford Kansas City facility that manufactured the Mazda Tribute. Essentially all Tributes during that time period were paint below Ford's minimum paint thickness specifications taht was used for quality control This information on the 2003 Mazda Tribute may be found in the book that we published on page 47.

automotive paints require a good clean and well prepared surface like light waterpaper sanding to remove any oily or fatty resedu and the correct undercoat before applying a new coatings otherwise it will not last chipping or peeling will occur.

color codes for paint are usually on a sticker somewhere in the vehicle. try looking in the trunk on the spare tire cover or somewhere in the trunk. Thats where I've always found it. There will be a series of letters and numbers. Write them down and visit any automotive store that also sells paint. They will have a book that will list paint codes for different makes and models of cars. Simply find your make, model and year of car and find the code that matches. Sorry I don't remember which set is for paint, but it's usually near the beginnig of the codes on the sticker.

possibly you are 180 degrees off.
the timing marks are dimples on the gears to align up.
paint will be no use at all to use and have never heard of anyone using paint .
use paint on a crack balancer for the timing mark ony

if you are using a mere touch up kit ..i would recommend for about 15-30 cents buying a model paint brush the bristles are much smaller than what comes in the bottle and no you wont need to sand it at all after application it will look very dull but put it on and allow it to simply apply to the scratch only ....unless you know someone in the paint dept...and ask for a bit of clear to mix into the paint it will look dull upon finish

if you are good at airbrush i would suggest merely filling the scratch in just as i described earlier ...unless you are going to actually paint the entire area then your talking blending into either the adjacent areas or merely blending into the area around the scratch ...what ever way you look at it touch up paint will always look dull upon finish

There probably a whole batch of them from the factory that weren't prepped right for the final coat... I think it's a factory error. I would complain to the dealer and the company. I don't think they use any cheaper paint, and essentially use the same techniques in painting the vehicles.

go to a body shop and ask for a tin and they will mix it ,but be warned its expensive as only new paint which is bio degradable can be used.1993 this is an old jam jar,i used to repaint with a hamiltons paint brush and some fleet teckaloid in my time,and if you couldnt afford the coach paint then a tin of wollies special and a cheepo brush
