I like to pre coat all surfaces that I will be gluing to with Tak. I  

clean the attaching surface with MEK, then sand the wood and scotch 

bright the aluminum and air blow and then clean again with MEK. 

Depending on how I am going to attach the fabric I use one or two coats 

of Tak and let dry before I ever bring the fabric to the wing. I like to 

glue the top of the leading edge down first, then rotate the wing so the 

cloth lays over the ribs and down past he trailing edge. I can then glue 

the trailing edge down by using 50/50 Tak and MEK the top glue the 

trailing edge. With the two coats of Tak already on the metal the 50/50 

goes through the fabric and activates the Tak under it. Then turn the 

wing up and use an iron at about 250 or so and turn the fabric around 

the trailing edge and onto the other side. On the bottom you can just 

glue it down and then cut the excess with a razor. When you do the top 

use something to hold your pencil the inch in to mark you cut. This is a 

straight cut, not a pinked cut, and it cuts better if you use some 

thinned poly bush were you are going to cut to keep the cut clean and 

neat. I use sharp scissors partially open and just run the cut--Caution 

do not attempt to work straight Tak through the fabric. It will not go 

and will look good but will not give a good bond. --- I then glue the 

outside of the outer ribs. That way there is no glue holding the fabric 

to the wing except the outer edge. I then shrink the fabric at about 250 

or just until it is good and snug. This has the advantage of not giving 

uneven strain on the ribs when you shrink. Now the fabric is pulling 

down against the ribs and the leading edge with no wrinkles. Simply us 

50/50 and brush the places you want to glue. The tension on the fabric 

will force the fabric into the pre coat Tak and you will see the glue 

ooze up through the fabric making a perfect bond. Do not soften the 

fabric around the edges while you are doing this as it will pull away, 

but that is easy to do. Remember to coat the fuel tank with several 

coats of poly brush to keep it from wicking the poly brush out of the 

fabric and causing pin holes. It makes covering a wing very fast and 

easy. I wish I could be there to show people the tricks that make it so 

easy.  Fabric is a lot of fun.

Great advise Allan, thats exactly the type of info I need at this point. I 

really thought the paint would go further when diluted with Reducer. This 

stuff is to expensive to make mistakes. Im not sure what you mean by 

"pre-coat", before applying the Tak. Can you explain this point further?.
