Engine case paint - street triple

[Ian Geary]

Morning all,

I've finally got round to sorting the cracked downpipes ony 2012 street triple.

Whilst the radiator and exhaust are off, I thought I might touch up some scabby paint on the engine block.








The engine is satin black and aluminium.

Googling suggests "vht case paint" satin black is a very close match.

But videos etc show a primer being used.


Can anyone share their success stories with repainting an engine block in situ?

The choices seem to be a vht primer, or an etch type primer (which aren't specifically vht rated)

My approach will be to
- wire brush the affected areas gently back to metal
- use high grit emery paper to get smooth
- clean with se sort of solvent
- prime
- vht case paint

Probably won't do a clear coat, as apparently triumphs don't come with that, and planning for engine heat to harden the paint.


Any suggestions appreciated.

Thanks

Ian

You’ll definitely need some sort of etch primer or the paint will just flake off, as I found out previously!

Your approach is right, it’ll be a pain to neatly mask off the bits of bike you don’t want to paint though.

I used POR15 on the Ducati, it’s brush on but flows well and you could lightly sand the most obvious areas gif a better finish. I think it would be easier to apply without risk of overspray everywhere.

Thanks for that.

Luckily I have a bit longer to do this now, as it will take some time for 6 new studs to arrive, and me to work out how to remove one that's snapped off in the block.
