These steps are mainly for a repair, you'd skip past the first half for a respray, scuff up the old paint with 800 or something and apply primer from there.

As for lightening paint, no can do mate, its paint fade. All you can do is make sure you either do an entire panel and blend to a line where light/reflection changes, or consider a full respray. A great finish on new work will be more noticable for the colour difference, so maybe dont buff as hard ;)

My only thought, is that, this seems like alot, I mean ALOT of work to get a single panel finished, so is this the same sort of process used for an entire car respray? because if it is, I would never have thought they did all this :(

How'd ur panel turn out?

Much luck or give up?

Ok, so here's wat i've worked out so far. (excuse the obvious being pointed out, a mate of mine yesterday was sanding back a layer of paint from a front bar with the dry 60 grit sandpaper for timber) so i'll try be thorough.

As much as the damage "doesnt look too bad" with some shiny paint left intact in places, be brutal. Its gomna be fixed, so dont try and preserve anything. Always easier to do a bigger area than blend a repair.

I usually start with 220 grit (wet n dry for all this, paper or sander in one hand, bucket and sponge in the other) for taking back paint, but for removing old bog or fibreglass, might go down as far as 80.

Take off a few layers of paint and see what you're up against, bog always binds better to bare metal too.

You can obviously mix bog correctly, fill and shape, its the sort of thing you'll wanna let dry overnight to be sure its set, everything takes time.

Fill holes with "metal fill" its a cross between fibreglass and bog. Harder to sand than bog, but so much stronger.

Once overfilled (always over compensate the shape you want) start sanding back with either 220 or 600, depending on the area being done, 220 for something the sander is going to have a lot of movement over, 600 for finer areas and corners.

Hopefully by now you have the shape you want, if not, repeat bog step above, only using 600-800 this time, being more particular to fine ripples or dips.

"Spray Putty" in a can is a godsend. Its a spray on, fine layer bog ideal for getting rid of stone chips or scratches. Allow about 5 hours for a generous coat of this crap to dry though, it can also undo a lot of hard work by "peeling" the whole layer off if u sand with too much pressure before set overnight.

Sand with 800 now, focusing on imperfections, air bubbles (you see these when the job is dry, so its important at this stage to keep washing down with water n sponge, and rag drying) and overall job finish. Ask yourself, is this ready for topcoat? By now it'll be looking pretty alright, but mulitcoloured. Base coat prime 2-3 coats now, and allow a few hours to dry.

Now that its all 1 colour, you're probably cursing at those spots you didnt feel or see earlier, so again make friends with the spray putty and sander. Get it right at this stage, or no amoutt of polish at the end will get you out of the shit you end up with.

Once happy, give a final coat in surface primer, allow to dry for a couple of hours, and give a light sand back with 1200 to smooth over. You're practically polishing it here, not removing paint, so focus on removing any scratches, and dont stay on the one spot too long. Wash with water and a sponge, allow to air dry, then use "prepwash" or similar to wash off remaining paint dust.

Happy with how it looked buffing with that shiny liquid? No dents, good shape? Buff dry, and check for pinprick holes from air bubbles.

Topcoat time.

Any acrylic in a can will do, but autobarn can mix any auto colour to a paint code, usually no more than 30 bucks.

3 even coats, allow a few hours to dry, then 1200 it smooth, wash with sponge and water, prepwash and allow to dry.

Clear coat is this process repeated, but dont touch with paper once sprayed.

48-72 hours is time required to dry for clear to be cut back.

Start with 600 to remove orange peel look, then 1200 to remove the 600's scratches, then 3000 to remove the 1200's scratches.

Finally buff with a cutting compound, and finish with a polish/wax.

This was originally a PM, but good info to share here. Feel free to add anything i left out or go into more detail. Hope this helps. :)

Great post explaining the process.

As a spray painter, It makes me sad when people still use acrylic :(

I'll second that! Acrylic should have been outlawed 20 years ago lol. Na it is good for guys who want to have a bit of a muck around but not much else. As for the title of this thread the only way to get that perfect paint job is to leave it to a professional and not just anyone do your research on the painters previous work. I'm all for people having a go and the more you do the better you'll get but painting 'perfect' 2pak is a skill that takes years to perfect.

yeah, 2 pack requires a booth and breathing apparatus if you care for your health. certainly not worth it for some doing a minor touch up or painting something like a grill or mirror.

Yeah you definately want an Airwash hood for resprays but no need with the smaller stuff. 2Pack is not the best for your health thats why I quit lol.

At the end of the day it's all about the finished product so if it turns out well then alls well but you would only ever blend solid colours half way through a panel and even then you need to prep it correctly or your edge will show/peel back when polishing the blend.

    • I certainly fall into the annoyed camp, but glad to hear that if it's happening at low boost then I'm not likely going to blow a turbo and end up with metal shards in my oil. Just feels like it prevents me from really driving it without hesitation and "peak" performance. Wonder if it's the VCAM, it did an impressive job of shifting the torque curve and faster spool, but maybe now it's "too fast" and there's too much air for how open the throttle is.  Based on some other threads, will also do some reading on synchronizing the actuators. They are the default actuators that come on the Garrett's and I would think they would be set the same coming from the factory, but if the turbos don't actually work exactly the same way at the same time as previously mentioned, it would be worth making sure the actuators are actuating together properly
    • I went down this rabbit hole before, ended up sourcing a motor from the UK (I'm in Japan) which also didn't function correctly. With the original motor, I disassembled it and reassembled it and it works somewhat, sometimes. What I could deduce from all my screwing around is that there is calibration of the gears on the inside of the motor and two ramps on the main gear which activate switches that operate the motor and move the sunroof either to retract into the roof or tilt. Where I got stuck was that, it seemed in my case that one or both of the switches that are activated by the ramp on the gear did not always activate and thus the motor did not move, causing it to sometimes not retract or tilt (apologies, I've forgotten which way it didn't work.).  Of course this part is discontinued at Nissan now, it's the same part in the S15 but no other models. I also contacted the manufacturer of the component for schematics - forgot the name, they're based in Gifu - but they declined to share the information due to being bound by an NDA, sadly. Looking through my pictures now, it seems I last had a crack at this in 2022. See, I so kindly wrote "open" and "close" next to the switches. If you figure it out, please do tell me. Those little switches, with the red buttons may need to be replaced.
    • It says 300ZX, does that make it an Aus delivered car? Funny how back in the day I just couldn't care less about Z32's and these days I am just in love with them. Back when Nissan was into pushing the envelope. 🤣
    • Hi guys, just after some guidance with an R34 sunroof that has stopped working correctly. It still opens and closes perfectly fine, but it no longer tilts/vents up or down. As a result, the rear of the glass now sags a bit as it drops down slightly in order to retract into the roof, but now it can't pop upwards into a flush position. I’ve probed the pins on the back of the switch connector with a multimeter and it seems like both switches (for open/close and tilt/vent) still work correctly. Any ideas on what it could be, or where I should even start in terms of diagnosing? I'm sure someone's had this issue before but I haven't been able to find anything online relating to this specific issue, most of the issues are with the seals leaking or the motor failing entirely. Thanks in advance!
