Hi @Maarten
As I've mentioned before I'm using polyester threads and to create on them tar imitation sometimes might be challenging. So it's necessary to have proper "mixture" which won't rub it off and will "stain" the rope properly.
My solution: bitumen
So far I'm happy with liquid bitumen from Idea Decoupage by Maimeri.
I'm pretty sure any other will work.
Process is quite messy...
I'm using jar with just a little of bitumen. Dumping rope inside the jar and using brush I'm dabbing bitumen all over the rope. Not too much because at the end you will wipe it off anyway.
When still "wet" I'm wiping the excess.
After couple hours when bitumen is dry using white spirit (mineral spirit) I'm wiping ropes again until happy with result.
In term of white spirit... the cheapest as possible.. fancy expensive from art shops doesn't make sense... I'm getting my from hardware store.
For standing rigging I'm not diluting bitumen. For running yes... to quite thin mixture.
Bitumen works great too with cotton as well.
However, for cotton ropes I'm using bit different mixture based on bees wax.
I'm finding more advantages in polyester threads rather than cotton.
Polyester is more flexible and doesn't get affected by seasons and humid or dry air. Cotton likes to hang loosely when air is humid.
However, polyester has also some disadvantages... and I think the biggest is that some of the threads might have quite high electrostatic force (like some of the clothes) which will magnetize the dust.
So... to defeat this we need to apply some anti-electrostatic solution
...and for this with help comes shellac
Shellac is natural solid organic low-fusible electro-isolator...
Similar characteristics you can find in: carnauba wax, paraffin, colophony (rosin)
Cheers,
Matt
