Congratulations, you've contaminated your system with leak sealer. Modern condensor cores have way smaller passages than the good 'ol stuff and get clogged by sealer. Now that you've made a mess of it, any pro you bring it to will need to solvent flush the system, increasing your costs significantly. Nevermind that any pro you bring it to will be weary of it since leak sealer can gum up the delicate valves in automatic machines or if your condenser is ever the same again.
You do not want to DIY A/C unless your idea of fun if buying expensive equipment. Do you have a gauge manifold? a refrigerant scale? a vacuum pump? now that you've contaminated the system, flushing equipment? and that's just for servicing. To find out what's wrong with it do you have a scan tool? contact thermometers, UV leak detection equipment? A nitrogen bottle?
