About removing the decals, at first I used a large black sharpie then found a high temp Matt black paint I’m modifying my fenders and the chrome supports once I’m done painting those parts I’ll post some photos, hope that helps.
So what worked for me was a large tip black sharpie while looking for a high temp Matt black, finally came across a good match . Once I prep the areas and fender braces I will post the results. Hope that helps
