I got a bottle of the 200mL size myself to try it out. But after doing the injectors, temp sensors, I'd like to get a 5oz. can to do the rest of the engine connectors. I did a search on eBay and all they had there is cans of D5. But since the Parts Express is in my state, I order stuff and get it the next day, so I'll be giving them my business instead of waiting a long time for some Ebay item. I tried some of the D5 spray ion the headlights connectors ( the ones in the engine bay) and I'm pretty sure it helped, but not as much as I think the D100 should. I even tried soaking some connectors in Evaporust. After I finish the engine, I'll do the headlights, then wipers, etc. Just don't spray it on skin; freezing cold stuff. th
