You're brave. I intend to get my car rustproof by Bolduc and ask him to install his mudflaps at the same time.I am working on a set of clips and a pattern for DIY mudguards
I do PPF here in Montreal and the mudguards are important with our terrible potholes and construction covering the roads with rocks.
I ordered a set of universal mudguards from rally armour and made a pattern.
Once I have the setup I like I can offer the clips pattern and exact drill bit (for the mudflap not the car lol) if anyone wants it.
