I had planned to use coke tin for cowlings for my 1/72 mustang but I can't get it to form round the kit part
and stay there, any tips on that? Or alternatives? Thinner aluminum sheet, toothpaste tube might work
wine bottle foil will be too weak.

Smash molding clear sheet I've done for canopies, could this be used with clear or white sheet for the cowlings?

Thanks for any help or suggestions.

Have you tried heating the panel up under a candle flame .

Smash molding will work just fine as well if not better .

Cheers Terri you never fail

Heat it and let it cool? or work it while warm?

Just normal white evergreen work for smash moulding?

If all else fails I'll bevel the edges so it looks thin.

,
you can always take "smash molding" the the next level and vac-form -
http://www.automodeler.com/modules.php?op=modload&name=Sections&file=index&req=viewarticle&artid=1243,
no special tools or equipment required, or use traditional panel-beating methods - make a pattern from hardwood and beat the shape using copper or brass plate (just remember to anneal the metal regularly), the book The Complete Car Modeller by Gerald Wingrove (ISBN 0-85429-946-7) cover's this and many other scratchbuilding techniques very well.
Any Q's on either technique just give us a yell and I'll explain more in-depth if needed.

Hi Terry,
ever tried Tomatoketchup tubes? It's soft and fairly soft.
