The trick is to live somewhere like Vegas, where it doesn’t rain...like ever. Just brush the dust off and good as new.
Here's what I use , they do a matte version to , no shine with the matte. I've just reapplied it, no washing before hand. Been three weeks and about 1,000 odd km since last use. Advantages are , hosing engine down once it's Cool enough to touch will restore 90+% off the clean shiny look. Bugs don't stick either ! cheers capt
Yes peeps i went for the GT85 And got my engines back and shiny again so happy with it. Does have a little bit of a smell when applying but short lived. Joe.
On naked bikes like the Triumph classic range, keeping the engine cases cleaned and protected is relatively easy so products like those already mentioned are adequate. For bikes with full fairings (like my Z) where regular fairing removal is a bit of a PITA, something more resilient is needed for parts of the engine not visible and hard to get at but still get covered in road crud. To this end I use Corrosion Block, a heavier duty version of ACF50 from the same manufacturer. At around £27/ litre it's quite a bit more expensive than WD/GT85 etc but worth it IMO. Spray it on, leave it, refit the fairings and your good for a seasons riding. Road crud still sticks but a wash with a good degreaser/detergent brings everything up like new.
