Craftmaster PPA additive

Has your high build undercoat gone like toffee with the cold or just thickened up in the tin due to age.
I found last weekend that due to the cold the high build undercoat had as previously mentioned, gone like toffee.
So I purchase some Craftmaster PPA paint adjuster. I added about 3% as per instructions and I must say I was well impressed.
The paint flowed a treat. Nice one Craftmaster.

An old thread , but I might as well chime in here..... Yes, my primer and my undercoat are half used and they have both gone quite gloopy, but I ordered some Additive, which arrived today, and I am pleased with how it has thinned them out.
