Hey guys, I hope this is a good area for this post.

I REALLY need some help with my covering job I am doing. Let me being with some of the details.

I am covering a CG Chippy and trying my best to do the Art color pattern in a way. First off the wing is covered entirely in ECONOKOTE white. The trim is being done with transparent Red and Blue Monokote.

Reason I am using this setup, is because I don't have a whole lot of $$ I can spend right now on covering. The LHS had a good deal on the Econo stuff, so I used it.

I was able to do the blue on the underside of the wing using both the Windex method and one section without Windex. So far both "look" like it is sealed. Only thing is, when I was trimming the blue, some of it started to come up.

I tried searching thru some post on here to find ways to control that, but never found anything on Mono over Econo.

So question is this. What can I do to make this work. I really don't want to have to strip the entire wing and start over.

Thanks,

Have you tried using heat? The only thing about covering over covering is a way to have the gas escape, so a woodpecker tool is used to poke holes in the covering being covered.

Yes, I have used heat. The iron I have is around 190, And I have gone over it several times. I just have not poked any holes

I never had any luck adhering monokote and econokote, tried econkote once, never again.

What kind of covering did you use for the trim with the windex?

So far I got Monokote to adhere to Monokote, SIG Aerokote, and Ultracote, but havent used Econocote.

You probably need closer to 275 degrees for monokote. http://www.monokote.com/monoinst1.html
Trim solvent http://www3.towerhobbies.com/cgi-bin...&I=LXHZ43&P=SM will stick it down.

So basically I need a hotter iron and use trim solvent??

I'd say one OR the other. Since you already have the iron, it only costs time to turn it up a little at a time until the adhesive sticks well.

If you are going to experiment with solvents & heat settings don't do it
on the model, use some scraps of the covering.

I shouldn't have to explain why! - John.

Yes and do what Boomerang said. Econo is not your best choice of covering, I do use it on small electrics and gliders sometimes but today there are much better coverings on the market. I did try it once on a big plane, a senior telemaster and tried to save some money, then I had to remove the econo and use real mono so I lost a bunch of bucks in the end.
The CG Chip is one of the better small stunt planes and you really don't want to cut corners on it, give it the respect it deserves.
I have never owned or used a temp gauge, when my irons temp is correct it is correct, I start out low and come up as needed then run it a bit warmer. Seems to work pretty well!

Thanks guys. I will get a new iron (once funds allow it). The one I am using now is a Mini fashion iron, and it does not have any way of setting it.

There might be a problem adhering Monokote on top of Econokote. The problem lies in that Monokote does take a higher heat to adhere... whereas Econokote is a low-temp covering... So.. yes.. your iron temp might be low for applying Monokote.. which is why it might not be adhering as it should... Herein lies the issue though... when you crank up the temp for the Monokote.... it will probably melt the underlying Econokote. Monokote takes about twice the heat.. easily. Econokote won't stand anywhere close to that.

If you had Econokote going over a Monokote base.. I doubt there would be any problem.. provided you turned your iron down to Econokote temp.. but in that case the Monokote wouldn't be affected.

If you've got part or more of it done successfully at this point.. I say very good, as that's probably a feat in itself.. might even be considered a struggle.. but the stuff shouldn't be that tough to lay down.. so if you've had problems.. what I'm saying might be something you want to consider.

Generally speaking though.. I'd say your iron temp needs to go up for the Monokote.. just beware the Econokote its going on is "low temp" stuff. I wish you well.
