OPP''S Now if I could only type and proofread yes you are correct spray 90 is the right one to use. I would lose my nerve using a belt sander to trim back laminate use a block plane or buy a router trimer bit with a ball bearing collar if you have gotten that far why take the chance and wreck it. tape off the solid wood and spray,after the laminate is done tape off the lam from the wood and refinish yes M.E.K. will take up just about any finish be careful with it and make sure you have plenty of ventilation! good luck with your project.
