QThe engine in my Honda Dominator is looking scruffy. What is the best way to remove flaking paint without dismantling the engine and working on components individually? The engine is out of the frame. I’m afraid that wire brushes in a drill or rotary tool will be too aggressive and I don’t want to start using chemicals that might cause issues with seals or gaskets.

AAlan Seeley says: Whatever you do, don’t be tempted to blast the engine – you’ll never manage to mask every orifice to prevent ingress of blast media.
Brass or nylon brushes are your best bet along with careful application of cellulose thinners. It’s a time-consuming process, after which you might wonder whether it wouldn’t have been worth partially stripping the engine anyway.
Just be thorough and methodical and you’ll get there in the end.
