There are other problems but the preparation of sanding is at the root. Even though you used the blotch control it's the density of the surface that determines whether the wood will blotch or not. If the wood isn't thoroughly sanded there will be places where the wood is more open and porus. These places I'm seeing have the green dot. Then when a board is surfaced there are places which the wood is run against the grain. This especially is found around knots where the grain runs every direction. There instead of making a clean cut it tends to tear making the grain really open and stains very dark. You can sand a lot of it out but sometimes you need to use a woodputty to fill these spots to keep the stain out of it. These places I'm seeing are marked with a blue dot. The red dots are surfacing marks like I explained earlier.

for the clear coat im using oil based polyurathane, to play it safe. I do not have a place outdoors to apply the clear so i am wondering how safe it is working indoors? I actually already applied one coat of clear, i had all the windows open and a mask as well one of the ones with the two filters on the outside. Once i finished I went out for about two hours leaving all the windows open while i was gone. I am only finishing one frame at a time, and only 3 sides of the frame (both sides and top only) the frames are 2' W X 4' H X 8"D so its not a huge surface im finishing.
I had some drips on my first coat, but i was thinking it would be best to add a few more coats to build up some thickness before i try and sand the drips, this way i am less likely to sand through the clear and mess up the finish?

Thanks again

The only thing you have to worry about using the polyurethane indoors is the flammable vapors. Depending on how much of it you have going at once you might shut off anything nearby in the house with a open flame. I just repainted a kitchen with an oil based enamel that had a room next to it with their furnace and two water heaters. I just turned everything off and stopped painting early enough in the afternoon for the solvents to disipate enough I could re-lite them before I left. I also turned off their refrigerator as the vapors hang close to the floor and a electric motor can ignite fumes.

As far as the drips or runs if you catch it while it's wet you can take a brush and smooth it out. Once dry you can take a single edge razor blade and shave it off. That way it takes very little sanding to smooth out. Sometimes when you try to sand a drip you end up sanding through the finish in the surrounding area before you get the drip level.

Is that purple heart?
Could you give me a general review on how that type of wood reacts to temperature changes? does it expand a lot or is it kind of stable? I wanted to do a project mixing it with darker tones, but I afraid of the reaction I might get once the project is done

Thanks!

I was not happy with one part of the finish so i sanded it back and started over.
used the blotch control first and on from there
I am getting a different look on this part it seems like the blotch control is not working like it did on fresh wood. I was thinking that maybe the oil from the stain is still there which is causing the issue with the blotch control

The picture isn't very clear so I'm not sure what the problem was. In your text " i sanded it back and started over" may be the problem. Anytime you take a finish off you need to use a paint and varnish remover. Sanding a finish off removes what finish is on the surface. You may be leaving some of the finish in spots that embedded into the wood and may be causing the stain to go on uneven.
