What is the colour scheme you are using? This will detemine how to go about weathering. I would also suggest doing your weathering BEFORE you decal, as I learned by my mistake recently when weathering an F14 after decaling where there are clear areas of decal, it wont weather and will show as a lighter or darker patch on the finished kit depending on your colour scheme. With naval aircraft you can over do it, dispite what some 'experts' say so be carefull. If you are using the three tone blue/greynavy scheme them preshading is quite effective if you dont apply to much topcoat colour. PM or email me if I can be of further help with colours.
