I thought I'd do a series of pictures showing how effective the POR-Strip stuff is
Like I say it isn't in the same league of 1980s Nitromors that used to try and rip your eye balls out of their sockets
POR-strip fumes are quite low. In a well ventilated area they are almost unnoticeable (but wearing a mask is best)
The series of pictures show a progress of the LH rear quarter panel over a period of approximately 90 minutes
For the first pictures all I have done is to brush on the stuff
The thinnest paint reacts the quickest (of course)
^^^ That happened after about 15 minutes
Here's an example of how thickly I'm coating the paintwork
This is about as thick as it will go on a vertical side - much thicker and it starts dripping off which, considering the price of the stuff, is the last thing you want to happen
About 30 mins in =>
Still just with brushwork (so to speak) - brushing the flakes off and applying more of the stripper
After about an hour of watching the paint peel I got the scraper out and gave it a bit of a stab
As you can see anything with a filler thickness of about 1mm or greater and the POR strip struggles
Here's what it looked like after about 90 minutes of soaking
The thinnest paint has gone.
The thinnest filler and paint has also gone
The other stuff where the filler is thicker than 1mm is still quite solid. The stripper doesn't seem to want to soak in.
At this point my patience has been used up and I will be getting the sanding discs out after a bit of a stab with the new multitool and scraper combo
I might test some of the last parts of the filler after the sanding to see if the POR strip can still cope with it when it is thinner.
