Works OK.

Piece of MDF. Aqua Coat half on the right, with the top-half of that left unsanded (so thick Aqua Coat) and the bottom-half sanded back


Undiluted wood stain applied.


The thick Aqua Coat results are patchy, the sanded Aqua Coat area is fine, if just a shade darker than the no Aqua Coat area. Then again, the pre-stain Aqua Coat area is also turned a shade darker by the Aqua Coat. And any finish on the wood will turn it that bit darker, even a clear coat.
