The benefits of Krown rustproofing have been discussed here. Krown-ing a vehicle does have some disadvantages as well. First, it requires drilling into doors and door jambs. Secondly, the undercarriage will attract dirt and working on the vehicle becomes less fun.
But the real problem arises when Krown comes into contact with rubber and plastic.
Our 2000 LX470 has been Krowned since 2005. Because we do not drive this vehicle a lot in the winter, we probably had Krown applied about 4 or 5 times since then - and maybe 1 or 2 more times on the undercarriage only.
Despite skipping a year (on average), rubber and plastic materials have swollen over the years. After replacing my headlight bulbs, I was unable to re-install the cover as a result of excessive swelling of the gasket. Especially softer rubbers become very gooey. Before the application of the Krown, silicone is applied to the rubbers. But this is only a temporary barrier. Krown will continue to ooze out from the weep holes and attack the rubber.
This is not a complaint. I just wanted to give a heads-up to anyone considering a Krown treatment. Going forward, I may decide to only have the undercarriage treated and not the body. Some Krown shops have offered to do this for a reduced price, but lately they seem to charge the regular amount.
Here are some samples of what to expect.
