I'm importing a 20 year old rust free Toyota to pa. I know the rust is inevitable, yet I want to delay it. A recent "drive" YouTube video displayed a product for spraying undercoat: however, more curious to me: they used paint primer before the undercoat.
Any benefit one could think of to the extra step?
Did not mean to post here. Guess I'll 'hafta upload pics when progress begins.
Id use an encapsulator before undercoating over a traditional primer. Either POR 15, rust bullet or Eastwood's offerings should handle the job without issue.
I would not apply undercoating, if anything cavity and undercarriage wax. If you don't want it rusting, don't drive it between the first application of road salt and the second heavy spring rainfall.

I tend to agree. Most diy undercoating is very thick but has low adhesion properties. It chips in one spot and the moisture gets under it. You are better off with, as previously mentioned, a paint type encapsulator like POR or Rustbullet (I prefer the latter) No need to apply anything over it, but regular paint is good if you feel the need.
