MISSION MODELS' GLUE TIPS

Any body have any experience using these tips? Got a supply, using ZAP Ca both thin and gap. Placed the tip on the bottle, not on the extended nylon tip, first time through worked perfectly.3 to 4 minutes later tried to glue another part and nothing came out. Tied both on thin and gap with the same results. Tried to contact Mission Mod for proper useage, but no reply. Tried to put the tip on the extention tip but without cutting down that extention, it did not sit right. Any help would be appreciated. Thanks.

Had replies from other forums, so I thought I share what worked because I did it. Soake the tips in aceotone to clear ths clogs!
