Subframe cavity protection.

[Goldsax]

Last year, I undersealed the body and subframe at shiltech.
They gave the car a glowing report, with very little corrosion.
I want to do it again this year...may be overkill.
Any idea how where the access area is to get the sealant into the subframe cavity (both front and rear)?
Thanks

Matt is touching my GTs underseal up as I write. He did it 4 years ago and it needs doing again in places. So yes it might be overkill but give it a good inspection, it might have come away in some places.

4 years for cars that live outside is about right. Anything more is overkill...assuming a good job was done which I can't see Shiltech not doing it correctly.

Its great to see that you're taking this seriously. Full marks.
But check the comments above from guys who know better than me and take this very seriously.

Keeping on top of it is the sensible way and should keep the subframes and underside in perfect condition.
If you take your car for MOT yourself then once a year you can ask your Tester nicely if you can take a look and what his thoughts are on how it all looks as trust me as an ex tester they will have seen some corossion.
Vigilance is the way.

she has not seen the rain and is dry stored.
i'll save the funds to update the sagging headliner next year.
thanks for the advice.
