I'd be giving Turtle Wax Bug & Tar remover a shot first. Its safe on paint.

Just recently started using it on a shell I am prepping, gets heaps of stuff off from gaffer tape residue, through to cleaning up tar from the floorplan.

work in progress guys, lost motivation when it got too hot. Chris tried a cutting compound a clay bar today - took a bit of work but it came off. Going to investigate other methods for the rest of them.

got some wax and grease remover from Super creep auto, might try that....

So 'in the wash' we now have...

Prepsol + Clay Bar + 2000 wet 'n dry + soap + cutting compound + mineral turpentine + turtle wax tar & bug remover + wax and grease remover + methylated spirits :woot:

...and oh yes, how could I forget; followed by wax :P

Hey Clint

Had something similar on my old 33 (From a seriously old Jap sticker). I used a cutting compound to remove, then a proper fine cutting compound to bring the clear back to perfect.

You know what I expect quality wise!

Haha, wish you had have given me the drum earlier, Rich!

I ended up using a combination of prepsol and wax and grease remover to soften up and remove the bulk of the residue. Then used a cutting compound (its called paint doctor and is pretty harsh) to get the stains out. Going to give the car a good wash and wax this weekend.

      And make sure the belts are tightened appropriately too.

      They care about emissions, and cost the most. Save weight where possible, and make manufacturing easier. Less material also let's the engine transfer heat to water quicker, and bring the engine up to temp quicker, better for emissions and getting them past their warranty period.

      I was under the impression the reason why OEMs are going with solutions like relatively thin "right-sized" cylinder walls with technologies like PTWA and open deck is because they care a lot about whatever marginal knock margin benefits they get from that vs the structural rigidity benefits of a closed deck block and thicker cylinder walls. I also see some weird stuff like plastic inserts in the water jacket around the cylinders to try and equalize cylinder wall temperatures. re: the PRP blocks and heads at the end of the day it's hard to know what is and isn't going to work there, just have to see what the initial buyers say about it.

      Which is why I didn't mention that hardness testing, and specifically mentioned the bore and deck thickness testing. Yeah, not really. The bore temperature will be a lot more even around the top half inch or so, where the material distribution is dominated by the deck, and which is the only place where the bore surface temperature heating any gas in the cylinder is likely to have any effect on detonation. Think about it. Another inch or so down the bore, you might have a hotter spot. The gas there might get a bit hotter, then the piston rises squeezes that gas away from there at high speed and mixes it with other gas from nearby. Instant dilution of the problem. I'd be surprised if it was an issue at any time other than in racing engines or OEM dev engines being run at the ragged edge of tuning. Say what now?

      https://dsportmag.com/the-tech/education/engine-tech-material-hardness-testing/ The PRP testing on block hardness I'm not sure how much it actually can be trusted. The thinner cylinder walls on RBs is a bit of a problem vs 2JZ but it really depends on the design goal. Siamesed cylinder bores like a 2JZ cause uneven cylinder wall temps too, which means a bit of distortion induced by that + the hotspot can affect knock margin. Something that actually gives me a bit of pause with the PRP block, whether super thick cylinder walls are going to keep it from being drop-in compatible on an otherwise OEM rebuild.
