The underneath of the supra prior to all the treatment was spot on, no corrosion at all, all cavity’s were checked etc, but it’s something I wanted done to protect into the future anyway, our uk weather and roads are shocking so it had to be done.
As your see the underneath was perfect before and even better after!
James removed all components, deep cleaned the underside, removed all surface dirt, grit/dust etc and any degraded under-seal.
She was then dried out for 48hours, and moisture tested.
Which is most important part to stop present moisture as any moisture left deems the future protection useless.
Some pics!
