Clear Acrylic Sealer Matte questions

Posted in Custom Workstation

I have a few questions about this. I bought a can after reading Kyle Robinson's tutorial on sealing figures. I used it according to the tutorial and on some parts it worked beautifully. On others it it stripped some of the paint off. Though I think that was because I had the can too close to the figure when I sprayed it. But anywho I repainted the messed up parts and everything looks good, but the parts I sprayed sealer on were kinda shiny even though I used the "Matte" and not the gloss. its not that bad though. I was wondering though will washing the figure with soap and water mess up the sealing job? I got some on parts I didn't paint and I wanted to know if I could like scrub those parts and maybe dull down the shinyness a bit without the paint coming off (Yes, I use the crappy apple barrel/folk art paints). Any comments or suggestions are appreciated. Please and Thanks in advance.
