Default Dope to Monokote HELP!!

Ok, guys so I just picked up a plane that I had wanted since I was little. A royal Cessna Citation. I got it totally ready to fly the only problem is, that it was covered in fabric and dope, then painted. The paint is white and it doesn't look very good now, it's yellowing and has some stain spots, and although it can fly the way it is now, I think this plane desearves a good finish. Since I absolutely hate painting, I was wondering if it is possible to strip the dope and fabric so that I replace it with monokote?

Yes it is possible to do but it will help to know what materials were used to finish it in the first place.

Start by using MEK (Methyl Ethyl Ketone) to soften the adhesive. It will generally soften all the adhesives used to attach the fabric except when the builder uses CA....ugh! It stinks but according to all chemical engineers I have spoke with it is NOT carcinogenic. All safety cautions obviously apply. Do not get it in your eyes, use a protective cream such as invisible gloves to protect the skin...etc.

The fabric should come off relatively easily.

Depending on how the fabric was attached it may very well just pull right off. Some guys use dope to attach the fabric and yes, it will pull right off. If it was done properly with the correct adhesive it's bonded pretty well. Ray Stits used to say "We have two kinds of builders. We have the ones that follow instructions then we have the inventors. The inventor always thinks he has a better way to do it reguardless of what the factory recommends". It still applies. Just look at all the different methods guys come up with to paint a model. Very few of them stick with the same manufacturer through the entire process.

Let us know how the MEK works out.

You might try your heat gun, just don't keep it in one spot to long. Also make sure you recheck all glue joints before you recover. I've stripped a couple planes of Monocote with heat and it worked pretty good, there is usually some spots that you have to pick off by hand ( knife ). ENJOY !!!! RED
