Default Bad paint/rust - touch up/respray panels or entire car?

Hello all,

I am in a slight dilemma regarding my car's paint's condition given that it is a tracked car that I would still like to use on the street for several more years

In a somewhat recent thread I remember saying that my carís paint is imperfect, but looks good to the untrained eye. I lied:

*GRAPHIC CONTENT*

Rust forming above left tail light



Rust in driver door jam



Driver side mirror is bubbling too



Rust-ish behind front driver side fender



Hood has permanent water spots (ceramic clear coat over them) and is fairly chipped up (repainted by po)





Passenger front fender is massively chipped (repainted by po)



As you can see, my M3s paint has seen far better days. It has 170k miles (likely driven in midwest winters for 100k+) and has seen a decent amount of track/autox/drift/street use since I got it (none of the damage was inflicted since I got the car, but some rust has grown slightly). The car was in an accident by a previous owner and as far as I know it the hood, front right fender, and passenger door were all repainted (euro bumper is also not original paint). These panels are a slightly different shade of Imola than the rest, though its not super noticeable unless the light is right:





I donít mind having relatively imperfect paint as the car is usedÖ let's say the way BMW intended it to be used, and rock chips are inevitable with track days, let alone drifting. BUT the one thing I worry about is rust. At this point Iíd like to keep the car indefinitely, using it as a street car for a while and eventually more track/weekend oriented, so I figure it's best to get rid of all rust asap, even if it's just some surface stuff (subframe is another story, but easy to replace).

To complicate things further, there are some other problem areas that donít involve rust or peeling paint, but could use addressing:

Touched up spot on roof (dark dot ~1.5x1 inch)



Passenger door handle clear coat is pealing



Paint spidering/cracking on rear bumper



Basically, Iím not sure if the best route at this point is to respray the entire car or to just respray the panels that really need it (though that could be.. a lot of panels). Most importantly I want to get rid of the rust; the appearance of the car as is doesnít really bother me otherwise. I figure a full respray would leave the car with a worse paint job in places (there is SOME original paint on the car) and be silly expensive. Respraying panels could be tricky and involve most of the car thoughÖ

Should I just address the rust areas and put as little money into the paint possible, or go all out + front end clear bra? Figure I can at least try to pick up a newer imola driver side mirror cap and passenger door handle from a part out, that's what I did for the other mirror cap

Thanks in advance

Before you say that I should've just gotten a cleaner car-- yeah, probably should have. But this was a higher mileage imola slicktop with the exact options I would have wanted (color is tough, but I'm happy with imola) that we bought to use as an autox/track car. Given what's been put into the car over the last few years I think it's safe to say we're in it for the long haul on saving this particular e46

I'm in a similar situation except I probably care a little less about the paint.

The rust will need to be taken down to bare metal, repaired and then repainted. I don't see another option. That is on the rear quarter so that entire panel will likely need to be repainted.

That's what I was worried about... and if I were to repaint every panel that isn't perfect I would end up painting practically the whole thing. I should probably consult a paint guy too

I'm basically fine with the car as is except for the couple rust spots that are on the chassis. Watching it grow is unnerving

I would fix the rust. It won't get better...just worse. They can blend panels so you'll only need to re paint the panels with rust.

I'm in a similar situation, my car's paint is not great and I would like it to look better. I've thought about just taking the exterior down to primer as a DIY and then have a shop repaint. Still would need to take the hood down to bare metal because of all the rock chips. Car paint ain't cheap either.

Man, in that condition take the car down to bare metal and full respray, otherwise you will be chasing the rust forever. The paint is clearly breaking down and it is a matter of time before another part bubbles up. Mines not even close to that and I want to respray it.

Expect to pay $10k+/- depending on how much prep you do. Changing color will be even more.

I don't think these cars are at the point yet where re-sprays are worth it over finding a better car.

I got a quote for $2k for my TIAG to have the wheel well and rear quarter panel rust fixed and blended. No welding, just filling and eliminating rust. It's expensive, but worth it. If you want to drive the car forever it's a no brainer.

Put me in the strip and respray the entire car camp. I am not afraid of a whole body respray but you better make sure you get a competent shop to do it. You dont want to be in this situation in another couple of years.

Yeah, I think you're right. Do you drive your car on the street frequently?

Yeah I'm thinking it might be best to respray as much as possible. I just don't want to ruin any existing paint that is good, as I know the respray will develop chips/swirls eventually anyway; my current paint is covered in an opticoat ceramic clear coat so where there is good paint its actually pretty solid

Yeah thats a lot... I'll have to contact some paint shops. No plans to change colors really

Not bad. I'm thinking in my situation it would be best to just fix the rust and not worry so much about the appearance of the car, but I don't want more rust forming later (I want to be confident that the car is protected). Hoods, bumpers, etc will see resprays on a tracked car anyway, but the main chassis part including rear fenders and tail light surround is my main concern. I'm wondering if it's feasible to remove the front fenders completely and just respray them separately from the rest of the car

Thanks for the input. That is my main concern here, if the car is going to be driven for many more years
