I found 3 fist sized rust holes in the frame of my 98 Toyota Tacoma. Luckily, a nearby weld shop is going to form up some heavy steel channels and weld them over the frame rails. After spending 350 bucks on the repair, I want this to last. What is a good spray on rustproofer for inside and outside the frame? The fluid film kit with special gun and one gallon of product is $150 plus tax. Given that the truck will last about another 6 years, is there a cheaper, effective alternative to spending over $150?
Thanks in advance for any advice
