Dear All
Is possible to paint SLC ?
I would like to use in my E-Legacy , apply in the wing sand with 1200 paper automotive primer , paint and clear
Do you think this will work ?
Thank you

Been done many times using dope, auto colors and Rustoleum. Get a green scouring pad used for dishes and pans plus pots. The shine off the SLC and paint it. Better yet why not put colored tissue or silk span on and the SLC per Larry Renger. Finally Larry I'm starting a plane to do that to. H^^

Thank you John
I did not understand. Sometimes my English fail .
Some questions :
Do I need To use dope with SLC?
A friend told me that SLC is applied like monokote .
If is equal monokote after remove the shine Do I need to apply automotive primer or not?
The same friend told me that I can't use in wing tip . SLC does not do curves very well round parts . Is this right?
Thank you again and sorry about my English?

Go on line to the corehouse site. home.earthlink.net/~philcartier . Phil has some info on the site, also there are some posts on here about using the SLC. Myself I use a hot air gun on the wrinkles that appear. But if you are going to paint over it the primer coats will make most wrinkles disappear. Like any thing it takes practice and patience. Do a search for SLC and plan on doing some reading and don't be afraid to ask questions. Have fun.

Today I did a small test
Apply a piece of SLC in balsa and use 600 sandpaper .
Then painted with DUCO ,
The surface is ok , I will apply clear to check the final result
I did a tape test and worked well
Thank you

I wonder what an E legacy is...fully sheeted wing or open bay?
If open Bay I think (and I love SLC) it is too light for this application without Poly span or similar as first coating
If SLC over a fully sheeted wing...the hard part is a perfect wrinkle free adhesion...but the finishing is real easy
I use SLC a lot on foam wings and have great success with using it OVER an already painted surface as the final coat...BUT I did do two planes intending to paint the SLC
Perfect wrinkle free application
Wipe with alcohol
Wear gloves
Very light scuffing with green Scotch Brite pad
Wipe with alcohol
Get in dust free area
Tack cloth away any static attracted dust
Light mist spray first coat.. follow recommended flash time for the paint
Second heavy wet coat
I do not do concours finishes and have never polished out a paint job (on a model airplane)
I did this with dull military colors so have no idea what an intended glossy finish would look like
Larry Renger's idea of SLC over the top of a poly span finish is a good way to fuel proof and get shiny top finish without clear coats or polishing
NOTE SLC is light enough to shrink and SHOW EVERY defect or wood grain once shrunk
BUT Super Light Covering is just THAT and not tough enough for open bays IMO

Why I canīt use in open bays ? One friend use in a model and looks very strong .
Do you think that with time this can make holes in SLC ?
thank you

I put polyspan lite on first to give the wing some strength then cover it with Coverite Microlite film, comes in colors so no need to use paint.

Your tests prove out that your procedure for painting you model will work. I think there is some confusion on your preference to paint the model. If you shrink the SLC per the instructions, it should be sufficiently strong. The other respondents are referring to a method that Larry Renger has pioneered combining coverings to avoid the mess and extra steps of painting and thus saving some weight. As Doc mentioned, a visit to Corehouse web site will cover all of your questions.
Good luck with your project,

Dear Dan
I visited the Corehouse web site , but my plane is F2B not to Combat .
Iīm looking for a way so to save weight and time to prepare my E-Legacy
Thank you

The SLC covering would still be adequate for your needs, I believe. Painting it should be no problem, as your tests have shown, but perhaps you could cover another model to test it to satisfy you it will perform as needed. It is used to cover large open structure combat models that are put through high G loads. I think that if your wing structure is sound enough, it will perform as you expect. Others have used it this way before and I don't recall anyone ever having a wing failure while using it.

I stand by my assertion that SLC is an excellent covering materiel BUT has limitations
Super Light Covering (SLC ) is real good on many 1/2a open bay type wings and a exceptional, easy to apply covering for foam or sheeted wings even on very large planes...
BUT I would never use it alone on a wing like a RingMaster or Twister without a layer of Poly first.. and when this is done (Thanks Larry R) you have a very strong/tight wing that LOOKS real good without the dope weight...
SLC alone does NOT have the strength of other heavier shrink covering like doculam, Mono/Ultra Kote for covering a 3"~4" X 9"~11" open bays
I keep hoping Phil Cartier will add his thoughts....
I like and use a lot of SLC
Super Lite and STRONG are many times mutually exclusive
Larry challenged all of us to try Polyspan ...no dope... and SLC top coat for a great looking glossy finished structure that was strong(er) and very lite...
I have experimented, and his method is sound and works well....BUT still, NOT as pretty as a professionally done 20 point polished finish the traditional way

I have covered several planes with SLC and no problems.

I have a Gieseke Nobler (open bays) covered in SLC and all I did was scuff with a green scouring pad, got it REAL clean and painted with Rustoleum high gloss enamel...no primer at all. The trick is to use the "can" just like you would a real spray gun...even and pass the surface with every stroke. Total weight gain was 5 ozs!!! Plenty strong and looks great. The Moon bros used to do this with great results. Mine's not a 20 but it ain't no dog either.

All I can say is if you've built a Ringmaster and covered it with just silkspan and dope and the covering didn't break in the air the SLC will be equally strong. The polyspan covering either over or under is way stronger than we technically need, but the polyspan does cover up a lot of minor blemishes in the wood underneath.
