I am going to be undercoating my RS with POR-15 but I need to know how to go about doing it. My floor pans are good, inside they still have the factory coating on them and underneath they only have the very beginning of surface spots throughout. If I took a picture you probably couldn't even notice them. So, what do I have to remove to spray the underbody? Do I have to remove the exhaust, driveshaft, all the suspension pieces, and fuel lines or can I just spray them too? I would have a body shop do it and want to know exactly what process I need to go through.

 

I just did my 89 RS and I took all may parts off so i wouldn't get overspray on them. I even did inside the wheel wells and the interior. Looks clean. I have pics on cardomain.com.(megatron1764) Just depends on how much you want to do, I am going to go over it again in case i missed anything.
