I have poured 2 resin layers on my most recent dio, which now has locked my bogged Sherman in place. Now, once the water is down, I need to add a little more groundwork, namely extra churned mud to really give the tank that 'ground to a halt' look... Bearing this in mind, there will be additional mud spatters etc. to be added to the tank, but my question is this...
Would the pastels/pigments dust stick to and discolour the resin water surface, even when fully drie/cured? Or would it simply brush off or be removed with a damp cloth? I need to know what level of masking will be needed...
Cheers for any responses

Here is what I mean... The [auto-censored] end of the tank is in the drink, so any weathering done on this side will be right over the resin soup...

And here's a fresh pic
