This is another project that I really hadn’t planned on doing this year but with the delay in getting my 1967 MGB GT back on the road it seemed like a good one to tackle. Having just replaced the fuel tank and painted the underside of the trunk a few hours to finish the job seemed in order.

I first cleaned the ugly trunk area about 3 years ago when the GT was still running. Check it out at Big relief, the MGB trunk area isn’t as rusty as it appeared. While this area wasn’t pretty at least it didn’t have gaping holes in it like so many others I’ve seen.

After a good sanding and degreasing I hit the area with etching primer and then a few coats of filler primer. Seam sealer was applied to fill in some of the gaps left by the hurried welding. The trunk area was never finished very well originally with lots of welding lumps, paint runs and areas with primer only. Remember, this is an MG, not a Porsche!

After sanding the filler primer and installing the fuel tank beneath the trunk looks pretty respectable. On the original 1967 MG this area was painted body colour but I’ve decided for now to once again apply a few good layers of undercoating to the panels. It looks good and can always be painted body colour at a later date if wanted.

Here it is with 3 coats of undercoating applied. I also painted inside the tail light areas that were badly painted initially. The only problem I’ve run into is that at some point the previous owner (my dad!) used silicone to fill some of the gaps and holes in the trunk bottom. I’m having a real problem trying to get primer or paint to stick to these areas. On the right you can see where I’ve resealed an area with seam sealer. Hopefully some paint will stick to that
