As some of you know I am working on a Shasta. I have replaced the front panel, back panel and a few side wall pieces. I tried something new and put a couple coats of shellac on before installing the panels. I made the assumption that, as with my last two campers, the old wood would match (with some work) if I sanded down to raw wood. As a test I sanded a piece and discovered a deep brown stain had been applied at some point. I worked it down to this raw condition... Then I applied 1 coat of Amber shellac and something unexpected happened. Bottom is new wood I want to install. Top is old wood, sanded clean with one coat of shellac. It appears my options are darken the new wood dramatically to look like the 1978 basement paneling in the house I grew up in (yuck) or paint everything. Other options are more than welcome. By the way, I tried clear shellac only, 1/4 Amber 3/4 clear, same brown. I tried natural stain, etc, etc, and it always reverts back to dark brown. Really odd. I wonder if pre mixed Bulls Eye Amber can be tinted darker if I wanted to match the old wood? --- update: I ordered two Mixol tints that I believe can be added to shellac. They should arrive Monday.

I would consider a clear polyurethane in the old, just to see if it doesn't react to what is impregnating the wood

I'm thinking amber is the wrong tone. It is orangey, and tends to stay that way. I'd go clear and experiment with stains before the clear...

NC, there was a dark stain under the wash that was on my '62. I knew I wasn't imagining that!

I'm going to experiment with stains and tints but I have my doubts. I suspect this camper has different things going on in different places. The cabinet stain may be different from the old wall panels which may be different from the new ones.
My wife says if I can't get it to match really well, just paint. Slightly mismatched colors in several areas would drive me nuts. Plus a very dark brown like my 1970s basement is not really my thing.
I'm glad I didn't pull off all the good roof panels. If I paint there is no need to touch them.
Moving slowly is always best...at least for me.

I have methodically mismatched wood/stain/shellac. All the cabinet framing, door framing, cabinets and drawers had that dark stain. It's very obvious that is what it was because it is visible on the sides of the drawers where it doesn't show and the yellow wash wasn't put over it. I think that is why the 62 had that opaque whatever it was paint/wash/shellac. It made all of the wood look exactly the same.

Before you paint, maybe try a good penetrating wood bleach and see if the shellac looks better then?

Before you paint, maybe try a good penetrating wood bleach and see if the shellac looks better then? Good idea. I just tried Savogran Wood Bleach. This stuff has worked miracles for me in the past but the brown came right back. Amazing. I ordered tints from Amazon which should arrive tomorrow. I will tint the shellac trying to match the brown. Can we live with brown...that is the question. --- SusieQ, were you able to match the mismatched pieces to make it look even throughout?

I ordered an Oxide Terra Brown and Oxide Chestnut. I may try a slight red too.
I have been approaching this from the standpoint that the old wood must change. That isn't working. So let's hope the other side, changing the shellac color, does the trick.

The test has been going on all week. There are small pieces of test birch everywhere. Mixol tint added to shellac definitely helps. I tried Terra, Chestnut and oxide red. One coat over basic Amber and several. The problem is that when you add a lot the color is great but it has an opaque quality which obscures the grain. Here is where I am now. The photo appears more red than real world but you can see the tint difference. My wife says it's close enough but I'm still not thrilled. I ordered ruby shellac flakes for my last test. I will mix it to Bulls Eye Amber to make it slightly red. It will be a week before it arrives but I'll keep you posted.

Are you using ripped 1/8" plywood to cover the seams? If so, do you do anything special to the edges to make it look less "plywoody"?
