Technique for dirty windshield/wiper cleaned area?

[nuno81291]

Hey gang; looking for a non scale specific technique: I am trying to recreate the look of a dirty windshield that has been cleaned by the wipers. Perhaps dust or dirt. I was thinking something along the lines of using pastels as dirt, perhaps with the clean area masked off and hitting the dirt area with dullcote to help pastel adhesion. I can look for photos if this is not clear enough.

Thanks!

If I recall correctly, can hook you up with his method.  Paging @tom mann.

I do this by first airbrushing the dirt/dust/grime color over the model and then using a tooth pick to wipe clean the area that would have been cleaned by the wiper.

Similar to what Tom said, dirty the windshield then come back with a toothpick or micro brush with paint thinner

On 1:35 scale vehicles and larger, the easiest is to use Tamiya masking tape to create masks for the wiped area, place the masks on the windshield, weather the vehicle, then peel the mask. But  on smaller scale windshields masks would have to be really small. Probably not something that can realistically be done.

Thanks for the suggestions. I will find a scrap piece to try before the model. It is a 1/24 Revell pickup truck I am beating up on. Don’t think I could do it with masking effectively in N... maybe HO but that will be a later date.

Here is a good photo-tutorial on this process.

Masking tape on wax paper. Put in a 3 hole punch.

Use the circular punch chaff to mask off the windows glass.

It is easier if you do this before installing on the model.

Hit with fade and flat clear coat.
