hi mike
No just the playing cards. The neatness 'trick' is to watch as resin accumulates BEHIND the edge of the card,So while laying it down/spreading it out you have to manage that. Again when the card looses its flex wipe off the acumulated resin on the next new card and carry proceed,swiftly
Now the wing tip if you dare the card trick again does it for me... just flex the card to the curvature of the surface you are laying down-Lastly sight down your work like the barrel of a rifle and "skim off" any and ALL excess(should'nt be much.)
Last but not least ,if you can not resist or feel you need to: a paper towel or Mr. Whipple' and dab up any excess on the WING TIP ONLY,which will be all that os necessary and enen the compound curves of a wing tip are easily glassed using my adopted proceedure,that I heard or read some where some time.
