Guys, Can anyone recommend a filler for my Body Shell, a post on a replica forum suggested PCL polyprimer , "The PCL primer can be sanded wet or dry though, it does not absorb water or moisture of any kind. I usually sand it dry, but for the final sanding before paint its best to wet sand with 320. This primer uses the same MEKP catalyst to cure as fiberglass resin (mix about 1 teaspoon per quart for a 3 hour cure), it can be speed cured with heat if you're in a hurry without any problems.
The PCL Poly primer does not absorb water, it uses a catalyst, so I figured it would seal out moisture,I went searching for the product above to see if it was available in NZ , still not sure if its available here, but I did find these posts that I thought were interesting to say the least. Comments like this "I don't use Poly as it sucks up moisture like a sponge, not good on glass bodies and even worse on steel."
This now leaves me confused as I once painted a car and 5yrs later all the bondo started to blister and you could see everywhere it had been applied on a steel car, and it was wet sanded, and my Countach polyester shell will need some filling here and there, and I really don't need a repeat of the last car, any thoughts on what these guys are saying.
Spray on bondo pros and cons - THE H.A.M.B.
I am hoping someone from NZ, can reply with what is available and works in the NZ market.
Regards
Graeme
