SUPRA4EVA Posted April 27, 2021 Share Posted April 27, 2021 I read the hood is made of aluminum to save weight and I don't think I've ever seen one rust... Did toyota do weight saving in other places? Was that the only part made of something that doesn't rust? Link to comment Share on other sites More sharing options...
jim_supra Posted April 27, 2021 Share Posted April 27, 2021 (edited) The bumpers don't rust The removable roof section on Aerotops is made of aluminium also, however both the roof and also the bonnet can and will begin to oxidise and bubble up under the paint if the bare aluminium is exposed to the air by the likes of a stone chip etc. and is left untreated.

mc92 Posted April 27, 2021 Share Posted April 27, 2021 All the plastic trim, but that serves to trap water and grit which helps the car to rust so it still counts. Half of the front subframe is aluminium. So are the gearbox castings. Link to comment Share on other sites More sharing options...

Swampy442 Posted May 3, 2021 Share Posted May 3, 2021 The bottom frame under the radiator is another good place Link to comment Share on other sites More sharing options...
