The question was if anyone used micro in high build primer. I don't
see an answer to that only other solutions to paint. My answer:
I have used Micro in high build primer. It is worth a try. If you use too
much it makes the paint soft for a long time. I think if you work with the
right mix, which is enough to give you more body but not so much that it
does not get hard, you may like it. You can't fill anything too deep. The
method of micro in resin has never been very useful to me. It takes a lot
of sanding and never seems to get it all the imperfections. Of course if
you make a perfect substructure you are all set, good luck on that. In the
build process everyone has their own favorite process. The key is to find
the one that works for you. The 4" foam rollers idea is good and worked
real well for me. I got them from Home Depot. The other thing is, after the
high build primer and micro use a real good polyurethane paint and it will
help harden the primer. I am a long ways from a professional painter but
after trying just about everything I settled with that. This is only meant
to answer your question not to say this is the bets method.
