Finishing

[Lance Van Nostrand]

Thanks Tom,
I have a reasonably good painting setup, short of a fresh air system, because of the danger of isocyanates.  Fresh air systems are really expensive, but I try to do some of the painting outside when I can.  That's a much cheaper fresh air system, but sometimes you get what you pay for when bugs land in your paint!  

I am not happy with paints that need a clearcote to work.  I used the base/clear system on a few planes and it just doesn't last.  I build a plane from the ground up so that it will last over 1000 flights and all components are targeted at simplicity and durability.  The base clear system sometimes works, but often requires repainting.  Chips are normal, but get fuel under them and migrate.  Dripping carbs or blown couplers blast paint inside the fuse which soaks through and bubbles the paint from the inside.  God help you if you have an accidental fuel tank leak.

I am keeping an eye on Klasscote paints.  they are epoxy, fuel proof and no isocyanates.  but no matching film covers.  I've emailed them with suggestions and they are small enough to acknowledge me, but no commitment on these mixes.

  No, No No...I was referring to the clear coat acting as a fuel proofing agent. Createx, as far as I know, by itself is not fuel proof at all.

  But a conventional Clear over Base system will now not have any potential problems in an electrified outfit.......as it can do in a conventional 30% nitro burning YS machine.

    So this stuff is fuel proof?  Does it mix with a hardener or just cure with heat and water evaportation?  I'm skeptical that something that doesn't crosslink can be fuel proof, but maybe this stuff actually cures into polymer chains like polyU glue?

      Steve/all,

      I have clear coated a few planes for a friend of mine who uses the createx stuff. I just used an automotive two pack clear coat. It comes up ok but is very dependent on the skill of the 'createx' applicator! If it is applied to dry and the prep work sucks-no amount of clear coat will make it look good.
      Infact I was blamed for the paint job!!! Nowadays-he takes his planes to a professional auto shop-and they charge him a packet of money with the same result. Works for me as its less possible exposure to the nasty stuff.

      I also believe there may be some adhesion problems with createx if not applied correctly.His stuff I've seen flake off ( i.e.; prep work!!!)

      My recommendation is to use the 'clear over base' system and just minimize the clear as it now no longer serves as a fuel proofing agent.

      Tom

         Nat over the last couple of years I have been playing with Createx Auto Airs http://www.autoaircolors.com/ they are water base paints that is used for airbrushing although they do need a clear coat to bring to a shine. They are extremely light and easy to use they just look dull as applied. They can be mixed and matched to anything and have 128 colors to choose from, theres a dealer you'll find on there dealer page called Dixie Art Supply in New Orleans http://www.dixieart.com/CreatexAutoAir.html I have only cleared with Lustre Kote which is not recomended by them, but maybe for the electrics you won't need the clear. Good luck.

          I don't know whether to use polyurethane, latex, watercolor or crayola. These electrics present all kinds of problems.
