prepping fiberglass areo

[YoungRookie]

My car is about ready to be painted, fixed all the dents. sanded it down, ect. Now what prepping should be done to the fiberglass bumpers sideskirts and fenders. Should i spray them with like a high build primer and sand them down smooth as well? What experience or tips does anyone have that they would like to share with me, i would greatly appreciate it. Thanks ahead of time.

test fit it and if it dont fit sand the edges utill it fit the way you want it. then mark you're mounting points with a sharpie and drill the holes to either zip tie the aero or bolt it on with small bolts and washers.

prepping a body kit is pretty much the same as prepping the body of the car...... just keep blocking it out and primering it then block out the high spots.....just keep repeating until the desired finish is attained!

Alright thanks guys.
Black flag- i beleivei have the same areo as you. Is yours the b magic? thats what i have. Do you like yours so far?
For the most part i have everything fitted up right, just needs to be sanded yet then sprayed with the paint, Im going with like an olive green.

Ya, B-Magic. Basically the predrilled holes for the front bumper were shitty, but I was expecting that. So I fiberglassed the behind the holes and drilled my own & attached with zipties. After that the shit fit fine. Rear bumper was basically spot on, didn't have to do much but sanding. One skirt fit perfect, the other was warped, so I took a heatgun and some fastener things to hold it down with. But basically it was dirt cheap so I didn't care...
