Hi Guys, just recently took on a project of restoring and older weathered table that I picked up for free. I stripped all the old varnish off the chairs, table (except the laminated top), and legs with stripper and then proceeded to sand everything. Today I sprayed on my choice of stain which in this case was minwax’s gunstock stain. But before I apply a poly clear coat tomorrow I was wondering if anyone has experience in applying an acrylic urethane catalyzed automotive clear coat to already stained wood furniture? I work in an auto body shop and have access and experience with a variety of PPG automotive clearcoats. Any advice is greatly appreciated! Thank You!

I’m no chemist, but I’d imagine that’d work fine, may want to give the stain an extra day to cure first, i’ve rushed finishing over stain once… and only once

I don’t know much about automotive finishes but aren’t they rather expensive and more of a health hazard?

I did a kitchen out of figured sycamore veneer that was dyed blue. Coated it with the automotive clear urethane and had no problems. High gloss finish buffed to a shine that you could see the color of your skin in the reflection.
Worked out really nice for me.

I think you would need to research the finish to see how it handles expansion and contraction. It’s a hard finish and depending on the type wood your using and where you live, this could create a problem for you down the road.
It would probably be ok for a chair or table leg, but IDK

If your in to mixing catalyst, I would just use a conversion varnish. That would give you the extra protection your looking for and it’s made for wood plus you could get whatever sheen you want. Go to Sherwin Williams or look it up online. It’s easy to use.

Also, it is advisable to make a test sample before trying any new combinations of finishing products. That will let you test adhesion before risking problems with the real job.
