I can vouch for the no Poly over R-A-F advice. When I used Poly over it - it peeled off like an onion skin
I've used Birchwood Casey's Tru-oil over R-A-F with good results. Though I've never tried lacquer. I have a 41-240 that I used R-A-F (it's really great stuff), now I want to add some decals and seal them over -- I'm not sure how to do that. I hope someone jumps in with some advice on what works over R-A-F.
