For the 2nd time in my life I am the owner of a brilliant engine with a dubious wrapping. I've just bought an R Reg 4TRAK and I am now looking to slow the corrosion I can see/feel already taking hold of it.
1st area is under the sills rom the rear edge of the door toward the rear wheel arch. It's only showing through slightly but if you apply some force to the base of the sill you can feel corrosion which feels like it's coming from the inside out.
Is it possible/worth applying wax oil to the inside of the sills? Is there any other solution? Or is it better just waiting till it really takes hold in a couple of years, cutting the sills out and getting 2 new ones let in?
2nd area is where the rear arches join theboot floor pan. It seems like the panels are poorly welded and that water is migraing up the joint from underneath. Currently i'thinking the solution is to get to the seem from underneath and blather it with underseal. If I vcan get to it without removing the tank.
Also in this area - what is the filler that daihatsi use. Some small parts are coming out. I could botch it with harsd as nails or liquid steel but if I can get the right stuff I may do that.
All comments welcome
