woodartist Posted July 13 Share #1 Posted July 13 Can you put a final coat of oil based poly over prior coats of water based poly. Which is preferred for use on model boats? thibaultron and mtaylor 2 Quote Link to comment Share on other sites More sharing options...
Jsk Posted July 14 Share #2 Posted July 14 I'd be leery of doing that. I've always read that you can put oil based paints over acrylics but not the other way around. The reason being that oil based paints will continue to off-gas over time. This traps pockets of gas which cannot permeate through the acrylic on top. However, acrylics don't (apparently) off-gas so the oil seems to sit on top just fine. Still... I'd think choosing one or the other and sticking with it would be the better way to go. thibaultron, paul ron, Canute and 2 others 5 Quote --jeff In Process: Skipjack Kathryn 1/72 Card (scratch build) Completed Builds: Slavic (Viking) Longship 1/72 (Falconet), US Revenue Cutter 1/72 Card (Seahorse), Link to comment Share on other sites More sharing options...

Jeff, Putting oil based poly over acrylic is what Woodartist asked about. So it sounds like you think it should be OK. thibaultron, Chuck Seiler, paul ron and 2 others 5 Quote “Indecision may or may not be my problem.” ― Jimmy Buffett Current builds: Rattlesnake On Hold: HMS Resolution ( AKA Ferrett ) In the Gallery: Yacht Mary, Gretel, French Cannon Link to comment Share on other sites More sharing options...

Having said that, I'm not sure what the difference is between poly and acrylic and how the passage of time would affect things. Maybe someone with furniture refinishing experience would have better insights?
