Our 04' PH top had developed a large amount of small cracks in the gel coat and eventually started to leak when it rained. After a bit of research I weighed my options. To have the top sprayed with LineX or Rhino Liner by a local shop was going to be $1200, even if I did ALL of the prep work. SMB West gave me a slightly lower price but I live 15 hrs from there so that wasn't going to work either. Instead of having it done I decided to do it myself and purchased the Raptor Liner that SMB now uses on their PH tops.
The Raptor liner comes in an easy to use kit that also includes the sprayer and hardener. I got it on amazon.com for $114 shipped. Not bad at all. I ordered the black non-tintable product because having a matching top is not that important to me since most of the van is black and dark green anyway.
The directions called for sanding and cleaning the surface in preparation and that was about it other than it did not recommend applying it in very hot temperatures.
I removed the cargo box, solar panel, awning and rubber gasket that was on the penthouse. Sanding took about 2 hours with a palm sander.
Next was masking and covering the van, this was a bit hard and having two people is a must!
Spraying began and was very easy to apply. I had the air compressor set at 50psi.
All of the photos show when the liner was still wet, hence the inconsistency of the finish.
I had enough left over to do my steps and front bumper as well. Looks great! I need to get a photo with all the stuff back on. We have had a ton of torrential downpours here and no leaks. The Raptor Liner is thick and waterproof. I applied 3 coats to the top, waiting an hour between coats.
For a bit of time and sweat, I got the top done for under $200 and I am very satisfied with the outcome.
