i made anti slip coatings on my NZLAVIII conversion using Gesso. i used liquid mask for where i didn’t want it to go then you paint on theme Gesso wait about 30 seconds then dab with a stiff brush in a strait up and down motion until you get the desired effect, if not rough enough add a little more then dab again. once dry remove masking areas. i should have done mine earlier in the process before i had fitted lots of other parts as it made it harder in some areas to get the masking off again
a trial i did first on a part i wasn’t going to use
masking removed and fresh painted
once dry
the brush i used
a with and without comparison
before
after
still shows through well once painted. you cake it smoother or rougher by how much you apply and how much you work it with the brush while wet.
you can see here some of the fun areas trying to get the masking out. that is why i say do it earlier in the build and mask areas you will later glue onto. you can cut the gesso layer with a sharp blade and peel it off if you added it somewhere you later want clear to glue down onto
