Bristol finish over epoxy

[mahoganizer]

I was wondering if anyone has applied BF over epoxy. What is the reccomended epoxy cure time before the Bristol application? I've never used this product before but am strapped for time and the 3 coats in one day is needed. I used Perfection 2 part last year on some woodwork (over epoxy) and have some white marks under the finish which I suspect is the result of overcoating the epoxy before it was fully cured.

No I haven't but I use a similar product by a different manufacturer.

When all of the solvents have dissipated from the epoxy, otherwise the Bristol Finish can strip the epoxy. Bristol Finish also needs to be well cured between coats. Also you must be immaculate in your working procedures. Not one hint of contamination from old brushes, residual chemicals or oil is tolerated by this material.

Correct.

When this whitening happens scrape the surface very lightly with a tungsten carbide scraper if you want to keep moving ... further sanding will not work until the epoxy is well cured.

Perfection for a non professional painter is as good as it gets from what I've seen. It is very expensive at $100AU per litre over here. I use Aquacote, but I certainly would recommend Perfection for use by non-professional painters after the results that I have been seeing.

Perfection for some reason, works. Polyurethanes are clumpy by nature but Perfection goes against this trend.

Thanks for the response Waiting for reply from the manuf. Sometimes you have to "cheat" a bit in order to get things done in time.
