if you are painting outside beware of neighbors houses and cars...
my friend fucked up when he sprayed his car outside and now he's got neighbors seeking legal action over the overspray on their cars...
fit the kit, then take it back off...
if its WW urethane then it should not need to settle much, should be near perfect fit right out of the box, but def keep that in mind if the parts are twisted in the box...
you always wanna drill holes and fit before painting...
drilling into fresh paint is nerve racking to say the least...
