Usually, No, but we can offer advice and techniques on applications of certain products that we have tested. We have researched and tested what we believe is the best combination of finishes that are easy to apply, durable, low VOC, user friendly, environmentally friendly, and look the best on our materials. We will be glad to send you extra material to experiment with different finishes and techniques. The door needs to be sealed ASAP upon receiving it, but in our experience it is best to do the final finishes by your local painter after the crating, shipping, and install.
