I have done many finish tests on Ipe. All of the oil-based sealers I tried (including Bona DriFast Sealer) have always failed these tests. Oil-based stains, DuraSeal and Bona DriFast would always dry and look normal, I don’t know the reason the stains passed and the sealers did not but this has been my finding.
Waterlox Original Sealer passed all my test and of course dewaxed shellac and water-based sealers always passed these test.
On the last three Ipe jobs we installed, sanded and finished our customers chose all water-based finish after looking at my samples. Water-based sealer, dewaxed shellac, DuraSeal neutral stain and Waterlox Original look very similar on the first coat. Waterlox made the Ipe turn slightly darker than the others.
My favorite is one coat dewaxed shellac and two or three coats of oil-poly.
The photo below shows dewaxed shellac on the left and water-based sealer on the right. As you can see there is very little color difference.
