24 hours went by and I was able to get the green to remove from the housing with just my hands, no hammers. Red needs another day, it looks like. It can't come soon enough. The fumes are really bad! I have to open my garage door a few times a day to air out. This technique should definitely be put in the advanced procedures in place of the claw hammer.

You do need to use a little common sense when dealing with combustable fumes. I should'a kept that little trick to myself.
One of you hi-tech Marquee guy's are going to blow yourselves up. Laughing

there's not that much fumes! It's just enough to annoy you. I didn't fill a tub of gas, just the groove. I think between two tubes, I at most used a cup of gas.

I do it outside. THe gas evaporates, so you need to refill it every few hours, but it works for me. Remember also that gas itself is not flammable, but the fumes are. Doing this in a garage is NOT a good idea.

Point taken. There are no cars or anything in my garage, so with the little amount of gas I used, I figured the vapor to air ratio would be no where near enough for ignition. I left the tube outside before I left for work today since it looks like it's going to be a nice day and I want the remaining gas to evaporate off. I hope the red will pop out this evening and I can move forward installing the new tubes.

Well, if we hear a loud BANG coming from Cleveland some time today, we'll know you were wrong about the vapor to air ratio. Very Happy

Yeah, but unlike Europe, I don't think a Phosphor plume will delay air traffic Laughing

Question for you guys that have used petrol to remove a tube in a Marquee. Did you bother to remove the face plate from the side housing? By face plate, I mean the anodized plate that the tube is caulked to. The reason I ask, is because that caulk joint was also soaking in gas, and because of that, has most likely been compromised. I'm thinking that caulk seam should never see glycol since the tube is caulked in place, and the groove is caulked as well, but wanted to know what others have done. The plate is not coming free, and I really don't want to get physical with it, for fear of bending it if I don't have to.

Thoughts, opinions? Nash, sounds like you removed it and then used the gas to remove the faceplate from the tube?

By the way, second tube came free sucessfully, garage intact Laughing

If you let the face plate and the part it is connected to, I call it the Cooling fins, soak some more you can use a knife to cut between the two and then use rtv to seal the two back together if you want to make sure it will not leak in the future. I did one this way because the RTV squeezed out on its own from the Petrol. About 1/4 inch of rtv ouzed out all around that tight seam. i was really surprised it did.

Thanks Nash, I think that's what I'm going to do. I don't like the fact that silicone has been compromised. I'm afraid even it it never sees Glycol, that it may interfere with the curing properties of the new silicone.

Yeah don't try to cheat. You have to much time invested in taking it apart to not do the absolute best job you can while it's apart. Plus i guarantee that if you skip something it will bite you for sure,it always happens, right? Well it does to me.

It does to me as well, and once the new silicone is in place, it will be a bear to remove.

To add to the petrol, I highly recemmend mineral spirits to clean up any residual silicone left on the faceplate. It gets in the grooves of the faceplate very nicely. A must for proper adhesion of the new silicone.
