That seems to be the best way for me.... I am a bit dubious of the hairspray tech. The reason I'm asking is when I did the 1/72 figures I primed with Vallejo then painted with Vallejo/
Revell acrylics and I noted that the Vallejo came off in chunks over the wee guys so I used IPA and then started again with
Revell 43 as a primer and top coated with
Revell and Vallejo paints and it worked a treat.
That plastisizer.
I went and got two cheap primers from pound land yesterday and think I'm going to find these rattle cans helpful
Cheers
