I recently used the RCS mask for the first time, I put down 4 coats leaving a day between coats to dry, when I cut the mask last night it started splitting along the cut lines and leaving gaps about .5mm wide... almost like it was stretched, so I have had to peel it off and start again, I washed the shell thoroughly with warm soapy water and dried it with a lint free cloth etc... Is there any reason why it could have done this ?
It has been kept in the house not the shed so it's not frozen at any point or anything daft like that and I gave it a good shake before applying to make sure it was mixed... I'm at a bit of a loss to think what went wrong
Any thoughts ?
Cheers,
Aaron.
