That was clever, much better as it stops the thinner.
Do you possibly have the name of the water based varnish?

Any of the usual types found at DIY stores.Check how the brushes are cleaned(the small print under directions)if water that is OK if spirits it is not water based.You can get glossy or matt,I ust matt.Normally from B&Q or Homebase

Maybe I was too quick there. Do you think the water based varnish will find grip on the nitrate dope?

Lars,did you mean dope sticking to the varnish?either way I have had no problems.I believe that all cars are now sprayed with water based paints and they have no problems with adhesion.

Barrie,
Did you sand the varnish before adding the coloured dope and on my can it says “dry three days”

Morning Lars,I dont sand,and usually leave structure outside in the sun to dry,difficult this time of year,but another plus,it does not smell,so you can dry it in the house,without the wife knowing.

I used Diatex on my K8 and had no problem painting it. I sealed it with a 50/50 mix of nitrate and butyl dope, so a little bit of shrinakge but not too much. Like Robbie said, the trick is to thin it just the right amount so that it brushes out (use a good quality flat brush) without leaving tracks, but it filled the weave.I played around with how much thinner I added (it is also temparature dependant) until I was happy with the results. I think I gave it three coats in the end.
I sprayed 2k straight onto it and a light rub down with a 3M green pad and a good wash down.

Hi John,
Yes, everything went well with the white paint it seems to be something in the blue paint which causes this issue.
Skycraft have now sent me blue dye to add; however, I am doing some tests and will report back soon.
