Old Contest Letters

I know this has been visited before, but it did not concern me, as I had no
glass airplane to adhere a set of letters too. As it stands, I am trying to
remove some painted on contest letters from both the wing and tail. I know
Acetone does the trick...But any suggested methods to apply it would be
appriciated!

Mitch... if you are flying a 1-26.. the contest number is the serial
number...

First go to rite aide and get your self a king size bottle of flexall
454 cause your gonna need it.

I went thru the same drill 2 years ago. It's all about elbow grease
and a well ventilated area.

I started out pretty sparringly on a clean shop rag and watched the
progress.

Good luck I think it took me about 12 hours to remove that numbers on
the fuselage and the underside of the wing.

Hi Mitch,
In removing old painted numbers, I first try to get the surface level (wing
up-side-down and fuselage horizontal) Then lightly sand the old numbers with
220 (this will help the acetone to penetrate) Then saturate a shop rag with
lots of acetone and place it over the numpers (wear rubber gloves) After about
5 minutes, start scrubbing. This only works with numbers painted over gelgoat,
don't try it if the ship is also painted with something other than gelcoat.
Keep er-sanding with 220, as necessary. After all is gone, sand the whole area
with 600 wet and mask and paint your new numbers, then wet sand and buff out
with buffing compound and a wool pad OR use *stick-on* numbers this time.

Lay paper towel wetted with acetone on the numbers. Wait one minute,
wipe off the numbers. Only works with laquer.

You might want to take a look at:

It's about an SZD-55, but there's a discussion in it on the effects of vinyl
contest numbers.

I'm having mylar seals fitted to my glider over winter. I elected to have
them stuck on the wing rather than rebated into it (partly for cost, partly
because you can't undo a rebate) and they are thicker than vinyl letters,
but set much further back.

Anybody got any experience on the impact of mylar seals on wing performance
and whether it's important to rebate them. Is it more important for the
upper surface rather than the lower?
