MarkYoungCrewChief Posted June 8, 2025 Report Posted June 8, 2025 A word of warning. This has been a very expensive and aggravating event. Even after washing the parts the Dupont 131S primer was not sticking to the resin well at all. I decided to strip it down and start over. In my experiance resin is immune to solvents so I dropped the finished cab and bed in a bowl of lacquer thinner to remove the primer. It did not take long to realize the resin was being eaten away/softened. There are some beautiful rust holes, not what I was expecting. The bed in particular is really messed up though the cab is not much better. I do not see any way of saving this holy blob of a kit. Thanks for asking.
steev Posted June 9, 2025 Report Posted June 9, 2025 Sorry to hear of the ruined parts. I usually test a non-critical surface with a q-tip dipped in the lacquer thinner to see if there is any reaction. It's rare but I have had some parts that would get tacky or dissolve. I've had some kits that didn't react to industrial acetone but I guess I just got lucky. I just recently had to strip the Tamiya primer from a figure that failed the "tape test". An old brush and Klean Strip Green lacquer thinner did the trick and solved the adhesion problem too. Thanks for the warning. Steven
