Patching vinyl seat covers?
While you're waiting for those new covers why not try it. You just might surprise yourself.
The only one I've done is for a seam on my '05 Ram driver seat bottom cover. It's held up pretty well for the $25 invested (maybe 5-6 years now).
The foam made it too tough to get the seam closed completely at the corner. The paint on color match has worn off but it's not separating........yet.
What I used may not be available today.........
