I know the unfinished exposed mahogany wood I have in my shop will darken when exposed to light. I think the UV protection might just slow it down. Also my cherry kitchen cabinets have darken over time.

Strange, .. .past experiences have shown me that Mahogany likes to turn a silverish color when exposed to sun for long periods of time.

If you want mahogany while it is uncoated expose it the amonia fumes.

My A.M. deck has darkened in the sun also.

there are a few hardwoods that will darken with age and exsposure to light no matter what finish you use and cherry and mahogany are the main ones although cherry will darken faster than mahogany and in less light I built my inlaws a grandfather clock a few years ago and where they have it near the window and the side that faces the window is darker than the other side now

My raw Sapelle lumber that I have laying in some sunlight in the garage has gone a bit more silver, but that sands off easily, almost like oxidization.

The finished, epoxied + clear coated sapelle and meranty ply dropped a shade, but nothing dramatic. More like 'deepening' the color rather than a heavy tint.

When I first started the project I intended to stain the lumber to darken it, but started to love the natural color and I read (somewhere, probably another forum post on Glen-L) to expect it to darken a bit over time with exposure.

I will be curious to see if Oliver IV's former color turns lighter again after she recovers it, and how long it stays that way if it does.

It appears the African mahogany does darken with light exposure and the Philippine does not. I plan on staining the sides and deck Chris Craft red and the cover boards and king plank dark walnut. If the sides do get darker it will not matter so much since the cover boards will separate the two red areas.. I also like the way the sides did darken a bit. I think the meranti also darkens up a bit when exposed to light.

Ahhh, ... Could be why I've experienced silvering in the past, mine is Philippine Mahogany.

Something to mention, ...

Philippine Mahogany IS NOT a true Mahogany. According to Glen-L's "Boat building with plywood" it is a member of the Ceder species. It just looks and acts as a Mahogany.

Shhh, ... Just don't tell it that, I don't want my boats to get depressed by thinking their built with imposter wood! :mrgreen:

The mahogany I have in the shop right now is genuine or honduras mahogany. I seen unfinished cedar fences gray with age around here.

Roberta,

I think you will really like Epifanes. I have used it for over 20 years and love it. I actually rolled and tipped my Zip. I used West System foam rollers, cut in half and mounted on a 3" frame. On the sides I rolled stern to bow and tipped gunnel to shear, or at right angle to the roll direction. On the deck I rolled and tipped the same direction, with the length of the boards. I have found that a little Penetrol will help the varnish flow and Epifanes really needs to be thinned about 10%. I've always used Epifanes Thinner but I'm sure others will work as well.

I'm anxious to see what a superb craftswomen like you will come up as tips for the rest of us.

The best part about a manual screwdriver is not needing to remember if you left it in reverse.

Completion is but one step in the process and not one bit more important than the others.

Look's really nice!! Everyone I know that has used Epifanes likes it, so Hopefully I will be among those.

Thanks,

Roberta :D :D :D :D

Three weeks of a lot of hard off and on sanding and I have finally stripped Oliver IV of all the varnish, epoxy, stain and wood darkening. I used about 45 sheets of 60 grit paper and a half sheet random orbit sander to do the job. Slow going, but the results should be good. All the low spots and little gouges are now gone and the boat is as smooth as a baby's butt. I will do some minor detailing, filling, and hand sand it with 100 grit prior to staining. If all goes well, I should be putting the hardware back on in December. We have a boat show in Milwaukee in January and I would like to be ready by then, but I will not rush it.

I was able to repair the caulking and it looks really nice now. If the staining process messes it up, I'll add a thin coat prior to the last two or three coats of Epifanes. I rebuilt the carbs and fuel pump on the Merc 500 and will be repainting that while waiting for the varnish to dry.

The African mahogany did darken while the Phillipine did not. The Famowood filler was a good match before the African darkened, but the darkening of the wood while the filler remained lighter in color was one of the reasons for the redo. Hopefully the Chris Craft filler stain will keep the tones more even. If not? :roll:

Roberta :D :shock: :lol: :D :D :D
