As subject really.  I'm using Eze Dope because I can't get hold of "proper" dope these days;  no LMS to hand and the Post Office are understandably wary of carrying flammable materials so mail order is out. 

Anyone tried Eze Dope for sealing?  If you have did it work? 

Know of any other reasonable, lightweight alternative?

Don't know if it is available in the UK, but I've been using Deft clear lacquer and Deft sanding sealer for years. In the US I can find it at some hardware stores but not at the big box places (Lowes & Home Depot).

Any of the courier companies will transport dope, get hold of Balsa Cabin, they'll ship dope to you through Parcel Force. It's worth getting a couple 500ml tins of shrinking and non shrinking dope and sanding sealer then. Chuck in some of their nice balsa and you're sorted. Probably looking at £8 - £12 pounds for a fair sized parcel.

Minwax Clear Brushing Lacquers and Sanding Sealers. https://www.amazon.co.uk/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=minwax+brushing+lacquer

Acetone lacquer thinner. https://www.amazon.co.uk/99-5-ACETONE-1000mL-Approved-Tamper/dp/B01MXE1LJC/ref=pd_cp_60_4?_encoding=UTF8&psc=1&refRID=TAQXJTBSD9FN3XBHNNCT

I have used this successfully on tissue models. It performs just about identical to the more standard model airplane nitrate dopes. Like nitrate dopes, you can dope over it with butyrate dope, but not vice-versa.

Had (had!?) to order some bits from VMC today so decided it was worth trying Deluxe's Sand and Seal.  If it means I can continue building in the dining room over winter rather than being consigned to the (unheated) garage (cos, "as any fule kno" dope stinks) it'll be money well spent.

Mike,

Is that Titebond Original wood glue?

1 to 1 glue to water mix?

Thanks,....Jim
