need some oppinions would i be better off just getting diffrent bumper cover or fixing that ugly one,just has bunch of scratches nothing major,but the guy i bought the cover from has a black one in mint conditionjust sandit with 220 prime and im done.or would it be better to just fix this one.then i know it fits properly not sure if they changed at all thru the years but that one is from an 81.

If its just scratches then I would keep it. Looks in the pictures like a chunk is missing on the left side. Is that just an illusion?

yeah its just because the cover isnt completely bolted on only by a few screws,the guy had everything off it ready to take it to the body shop and then his son decided he didnt want to restore a car.they also sanded it to the plastic there so its dark in color.

Be careful with it if you do remove it. It's quite a heavy frame in it and can crush the plastic and crack it. 78 - 81 should all be the same if you do go that route. Also you'll need to use an adhesion promoter if it's sanded down to the plastic.

thx rjuhasz thx for the warning about the heavy frame,surely wouldnt wanna crack it,was unsure if i needed the adhesion promoter or not as it will be sanded to bare plastic,the whole care will be sanded bare so i can start fresh again,on my engine compartment i wanna paint it body color but dont plan on sanding that bare or should i.

We had the car apart for years with the nose sitting on the ground and that's how I learned that about cracking it If you sand the nose to plastic you'll need the adhesion promoter, if you're just scuffing the paint and spraying over it you don't need it. It's always preferable to sand to bare so you know for sure what you have but you may not have to. You need someone smarter than me to chime in on this. I think it came with laquer paint so I'm not 100% sure that would cause an adhesion issue if you sprayed over it? I know a guy that had his entire paint job delam and he blamed it on spraying over laquer primer, but that may not have been the actual problem?

yeah i plan on sanding the bumper cover to bare plastic dont want any adhesion problems,but the firewall and inner fenders im unsure if i need to sand those to bare metal and my subframe as they will be getting 3 coats of por-15,then epoxy primer and then 2k primer and lastly the body color.the subframe will stay por-15 black.

You're not planning on using POR15 on anything but the subframe right? and only if it's rusty. Check the tech sheet on it, I don't think you need 3 coats of it, I've never used more than 1.

i was gonna use it on my firewall and inner fenders but not such a good idea i take it,no there not rusted at all just wanted to prevent any rust in the future.maybe just prime and paint then,the only time i ever used por-15 was on my 80 camaro but i used the white and it took 3 coats to cover it.no my subframe doesnt seem rusty,what kind of paint should i use on that then.
