note to self in case I ever do this again.

Heat forming the edges with a 225 degree F iron helps a lot.

Purchase a roll of 3 or 4" wide finishing tape for the trailing edge.
Sure one can cut it from leftover material like the manual says but you
will have a crooked tape line and spend a lot of time ironing out
wrinkles and creases. Not to mention a certain amount of frayed edge
even with pinking shears. :(

Purchasing a roll of 2" tape was a good move :)

Follow the Polyfibre manual and do the first coat of polybrush befor
applying finishing tapes. Then apply another heavy precoat under the
tapes and let it dry. Then coat it as heavy as possible and apply the
finishing tape. After it dries, dry spots (air) will still appear under
the tape, but not near as many.

I am pleased with how the fabric went on to my flaperons but am less
happy with my finishing tapes...

This one has been mentioned before but I found the $10. polyfiber book
invaluabe. If you buy the candy thermometer for $9. as the manual
recommends for calibrating your iron, suddenly the $20. practice kit
from Spruce becomes an excellant investment as it includes both items
and more.

Hi all



So gona do fabric this weekend, but one question, when you do curved upper
surface and then fold fabric down sides, do you cut the fabric to overlap
the edges or just fold over itself like pleats



Thanks

i am having trouble with poly fibre polybrush sticking to the metal of the
ailerons, i have creaned and scuffed with wire brush but it does not seem to
stick very good, the poly fibre book says to coat all metal and wood with 2
coats of this stuff before doing anything, then the poly tach cements the
fabric to the metal

the tapes are supposed to be suck onto the fabirc with poly brush too, i
cant believe this stuff could stick toilet paper down

any help would be great, i think i may to metal and then balance the flaps,
sure would be less hassle and less poisoness
