Putting letters onto a kit.

Perhaps consider using rub-down lettering (Dry transfers). These are available in just about any size and typeface  you can imagine.

The oval outline... Cut a thin sheet of plastic into an oval and use it as a stencil.

that.

Also at the same store you should be able to find drafting templates that will replicate the exact oval or square you are seeking. 

Thanks I'll look into it. 

before I go out and buy dry transfer decals I would rather just buy a clear waterslie priting paper and make a decal for it.

Look in the model railroad section of the LHS for dry tranfser commercial signs & logos.  Dry transfers beat waterslide hands-down for ease of application and look just as good.  I use dry transfer lettering for aircraft squadron codes, unit bumper markings, pilot names on canopy rails, names on gun tubes, etc... Can't beat 'em with a stick...   

Yea, only problem is my local hobby shop has nothing
