Actually leaving the plastic on can make thinks a lot worse. Scotch Brite, clean and Build on. If you wish, a light coat of self etching primer.

Quote from: SECTION 5: CONSTRUCTION MATERIALS, PROCESSES AND USEFUL INFORMATION

Quote:
Van?s Aircraft does not have an ?approved? primer. We use Sherwin Williams P60 G2. This is used on the QBs and prototypes made here. The QBs primer has no pigment so it just makes the interior surfaces slightly darker and less shiny. In the US, this primer has a green tint, so the two will not match exactly. We use this primer because It is inexpensive, dries fast, and is easy to apply. Sherwin Williams will tell you that the primer needs a top coat. True, for optimum corrosion resistance, but Vans feels that this is not necessary for the way in which most owners will maintain their RVs.
Are the parts primed before rivet work to QB kit (fuselage and wings) or is the QB kit primed after rivet work? If QB kit is primed after rivet work!! For those who want the RV- well protected against corrosion and bad climate, will it be best to buying standard kit? This requires, aluminum plates can rivet together and the parts can be primed first?

I do not know if the factory primes before or after assembly in the QB's. However, the wash primer they use only offers marginal corrosion protection by itself. For most, that level of protection is more than adequate.
If you are concerned about operating and storing your aircraft in an extreme environment, and feel you need the most robust protection possible, on and under structure, you would be better off priming before assembly with one of the two part epoxy products.
Corrosion X is also popular and gets excellent reviews, however I have never used it or been around anyone who has.
