Wedge Adding Blue Devil head gasket sealer

Hello all.
I picked up a 1980 TR7 last weekend knowing that the head gasket was probably leaking. After draining the oil today, I'm pretty much certain. I have spoken to several people and seen many positive reviews on this head gasket sealer. I figure it couldn't hurt to give it a shot. Question is, the instructions state to pour it into the radiator through the radiator cap. With my TR7 not having a cap, where would one pour it into the system?
Thanks

As a quick temporary fix and has been on the market for many years and has proven successful in many cases. Bars Leak.

How about pouring it into the Thermostat housing...after you remove the thermostat and draw out enough coolant to make room for the stop leak ?
Have you heard about the black pepper 'fix' ?
Which ever...plan on removing the head and seeing what's really wrong...it may be more than just the gasket.

Question, how do you ad or fill coolant to the system normally in a TR-7? Needing to wrench off a part to ad coolant seems ridiculous!

Use alumaseal or the bars leaks product Paul likes. Access point could be the top hose (#6 in the Moss diagram). Loosen it from the radiator, remove it from the therm housing, rotate the hose and pour the stuff in.
