Acrylic extender

Anybody recommend an extender to use with Tamiya bottled acrylic paint? Getting fed up with ‘instant drying’ and brush dragging.

What about with Humbrol acrylic spray paint? Getting fed up with it powdering on impact.

Tamiya has a paint retarder for acrylics. It comes in the same size bottle as their thin liquid cement, but it has a light blue colored cap.

I have used Tamiya’s acrylic retarder for brush painting. It has done wonders for brushing it - no clumping, streaking, just smooth with great leveling. I have a Fairy Swordfish awaiting paint so I might forgo the airbrush on this and go with the brush and Tamiya acrylic to see just how good I can get it going “old school”.

Have yet to try the Tamiya product, but I have used Future (now sold as Pledge Multi Surface Floor Polish if I remember the name right). It really slows down the dry time and gives the paint a semigloss finish. Sometimes that’s useful.

There was another thread about this where someone was using a Grumbacher acrylic retarder to help with brush painting, maybe worth looking into if the Tamiya isn’t available.

I had never thought of using retarder for brushing, or with acrylics.

Thanks for all the replies; if I had a Homer Simpson ‘doh’ emoji I’d be using it now. How stupid am I not to research Tamiya’s own products? I should have known of course. Still, always good to hear people’s opinions.

On the subject of Humbrol acrylics, I’ve found a product called VMS SlowMo airbrush extender which is claimed to be Humbrol compatible. Has anyone used it?
