After removing excess rust off a Victa full crank engine cowl and and briefly wiping with wax and grease remover, the combination undercoat and rust converter lifted off in spots the next day as I went to blow dust off with an air gun.
Was it because I was too light with the prepsol or the fact it was quite late in the day (4:30pm) and chilly outside? The can states to apply between 10�c -30�c and it felt like it was no less than 15�c.
One thing I did notice is where the metal was exposed, the product did convert the remaining rust quite well.
