I have used a lot of Eastwoods Corrolless but never POR 15. From all of the
acounts I have read about the use of POR 15 I do not know why I would ever
switch. Corrolless is very easy to use and clean up. It does not need to be top
coated and you can paint over it without using any special chemicals applied
within in a certain amount of time. I did the whole underside of my 57 23 Window
and it came out excellent. One advantage there is that it is almost the same
color as the old Ceiling Wax Red that VW used on the deluxes. Another big
advantage is that you can get Corrolles in spray cans. One note on the spray
cans is to use the whole can at one time. They have a real tendency to plug the
spray valve if they sit to long. I am currently finishing off a quart can of
Corrolless that I have had for the last 4 years and it is still good. That and
no Isocyanates make some pretty huge advantages.
hope this helps,
