How to make Fender Flares?

[STEADYDIPPED]

Thanks David. I added some racing stripes last night. Cut and laid down some masking tape. Outlined tape while on model from front to back with X-acto knife. Painted in between the lines as best as I could and wallah! Final detail will be painting tire decals and maybe adding front and rear window tint?

I'd try the grit sanding sponge if it wasn't such a tight squeeze but, unfortunately spray is on the interior windshield.

Thanks!
