Thanks guys - yeah I realised it was too early to sand soon as I'd noticed it. So I haven't been back with the sand paper since. Given what you've said I'll just keep going and hope that it evens out.

I saw a vid that says you should wipe off the excess - I thought this might be the cause of the lumps. But I'm having trouble doing that before it's too dry and leaves drag marks. I end up putting more back on to fix it.

Of course I'm refining my process with each coat - but putting just a smidge on the rag is enough to easily cover the top. I'm using the excess to the cover sides. I only have to go to the back to the pot cover the back and then it's really easy to overload the rag and end up with runs or drags when I hang it up.

After your last post I took the scissors to my rags and chopped them down to about that - I think have plenty to see me through.

I'll post some pics later today of the progress.

One thing that struck me - I should be poly'ing at least five bodies at a time - it would be way more efficient! But I'm not sure I can plan my builds that far ahead.
