Humbrol Clearfix

Anybody got any experience of using this stuff? I've had a bottle ten years and never opened it. Is it as adhesive as your regular poly cement, and can it be sanded when dry?

 

Thanks

1. its a PVA adhesive

2. no it cannot be sanded, at all, ever

3. Its best use is for attaching canopies.

4. it can be used to 'glaze' small windows or to fill in landing lights

5. it shrinks as it dries, and keeps on shrinking

6. its useful to have in the modelling armoury

7. once you open it it will start to set, to thicken, eventually when you've still got 98% of it left in the bottle it will be too thick to use

8. I've tried many liquids but I've not yet found anything that can thin this stuff to make the thickened useable again

A follow up now that has been brought to my attention again

1. its not quite a PVA glue but is neoprene based

. . . .

8. Evo-stick contact adhesive Cleaner thins it. I have revitalised three bottles of Clearfix which had thickened to the point of being unusable and ready for the bin

That is interesting, I may soon be in a position where I need to try that! I certainly was a couple of years ago when my first bottle thickened, then I bought a new one and it too was thick and unuseable.

 

Thanks for that idea,
