Be careful of the high-build primers as they are soft and will not resist bumps and bangs very well.
Actually - a good catalyzed primer is the best as it will set HARD and it will not react to almost any overcoat of paint no matter what you choose.
I tend to use aviation dope - non-shrinking kind and mix in some baby powder for a filler. It sands really well - smells sweet and won't clog the sand paper.
Aviation Dope may still be available in your hobby shops that cater to the old tissue and Ceconite fabric built models. Try an aircraft specialty supply too.
There was one in Fullerton, CA on Truslow Street - but I know they moved. They were the biggest source of aircraft dope for me for my years of aviation restoration and RC building. It was specifically called: "
Aircraft Spruce & Specialty Supply", and that's the place where a lot of Rutans got their parts and product.
I am getting no results and I think that either their server is down or they are gone.
Nah - I think it's a server thingy. Try them later.
Either way - Testor's and (d@mn it - I cannot remember the other name of the supplier for dope!!!) it should still be available.
I can mentally 'see' the label too! Rats! The doc said it would start this way.............I guess ya gotta die from somethin'! Huh!
But ---> I have a few gallon cans of it yet. I can see the label, but can't find the word on my tongue.
Don't get old.
