Ah, the retrieval of wayward models....a challenge as old as aeromodelling itself.

Cockpit tray moulded and fixed to frame. Just going to run some cf tows around the outside to stiffen it and give more gluing area for canopy.
I seem to be stuck in an endless circle of filling/sanding with the fuselage. Just when I think I’m ready to spray, the light catches an imperfection. At some point I just need to man-up and shoot some primer at it.

Looking good Roger, only problem is you see more defects after spraying on primer !!!

Hi roger I use isopon reface great stuff. Looking good

Chris - I know! It's going to look SO BAD when sprayed.

Roo- thanks for the tip. I've never sprayed 2K and don't think my health could handle it now. So I'll probably use a rattle-can primer and just accept it is an inferior result.

Rog, another option is to brush on 2K primer over the worst areas. You need to do some industrial-scale flatting, but you can start coarse (120) and work your way to fine (600). This will leave you with a surface with all but the largest imperfections filled. Aerosol primer is so thin in order to get it out of the can, that it's about as much use as a chocolate teapot...

Hi roger I do not spray it I brush it on .it sands really easy. Stopped using micro balloons has it makes me feel ill when sanding even with a mask. Also I use 2k stopper to fill small holes.

Thanks Chris and Roo. That’s good to know. I’ll order some. I assume although it’s polyester based it’s compatible with epoxy GRP.

Interesting what you say Roo about the microballoons becoming a problem for you. I’d never realised until I read the label last week that you should have a mask on before you open the tub.
It’s true, and worrying, when they say that whatever material you work with ends up inside you.
With composites in particular people develop sensitisation over time, to the point where even a trace of the substance will trigger an allergic-type response.
And it’s harder than ever to get PPE at the moment for some reason?

I use this stuff, especially as it's available in white...!

Thanks again Chris. Good enough for you.... definitely good enough for me!
