I do coat on Bergger COT320, a cotton rag paper. It works out very nicely, but rag varies from batch to batch and therefore you would have to adjust the formula for the batch of paper. I have also coated on Strathmore, Cranes and Lanaquarelle.

Basically it is a surfactant issue.

Baryta paper varies as well, but for a different reason.

I forgot to add that this summer and fall, I will be showing examples of coating contact paper on all of the above.
