I admit it. I'm fed up. After years of throwing away CA bottles because they got so screwed up you had to cut them in half to get the CA out, I'm ready for some tips. The topper was when I decided to try Pacer CA. Their bottles are the worst on the market. You can't take the tops off to clean them out. Yes I know you can soak the tops in acetone and desolve out the dried CA. So far that is the only solution I have found to the clogging question. it seems no matter how careful you are cleaning the tips it's only a matter of time before they clog up. I'm open to any tips anyone is using.
