Thanks everyone for the compliments I'm pretty proud of what I've done so far but always looking for the next step.
EZLip looks super easy and is great to know as a back up plan.
The car only came with the passenger door monsoon, managed to source a driver's door one at a Subaru Spare shop in Hamilton.
Pics of the lip as it currently is below, sanded back with a good coat of primer in prep for a light sanding before painting it black. I should also point out that the lip has been plastic welded back together after a crash I believe, really hoping it didn't get shorter in the process
