Hi, new here. Just another question to Future (would like to add on to it, since there are a few threads of same topic around, thought I just add on to make one single thread more informative), I've used this stuff to strengthen some of my flat acrylic paints, and had this stuff for two years now. I recently saw the finish on two of my model cars starting to have cracks around, those spider web types, now my car looks like an ancient vase (those that have cracks on the pottery). I have yet to see the finish on some of my friends model cars (I did the body paint jobs on them). I've read other forums about Future cracking and stuff, which is probably due to gas out/drying process of paint underneath, and many people have also advised to not use it but use something else instead. I saw some fellow members here showing their future applied cars (gotta say, very professional level to me), and I would like to ask some fellow experienced and positive experienced members to describe the procedure to applying this (in terms of when after the paint job, in layers, or just once, and the timings etc, what kind of paint was used underneath). I use acrylics paint underneath, (tube or bottled ones art brands from art store that I mixed with future, which is quite strong and cost effective, but I really want to fix this Future clearcoat problem).
Edit: I am starting to suspect this problem is caused by polishing, maybe a reaction with polish, since my with friend's paint jobs I never polished, just lightly waxed. Maybe if it's not a reaction with the polish, it's the rubbing action moving over the soft acrylic softening the paint and causing the hard clear to crack.
This Williams was done with Future, but cracks started to show now, they are small and all over the place, I can see them clearly from 10cm away and angled with light hitting on it. I'll probably try to sand down the clear and apply a thin layer to fix it.
