After the rear panel is installed you can begin on the doors, keeping in mind the rear must be in position as the doors will attach to the Velcro stitched to the rear panel. Again aligning roughly each door to mark the areas where the Velcro strips will need to be attached to the roll cage and body panels. On the body panels the rear of the door follows the body contour and on the front fender side it will follow the contour of the front fender. Here it gets interesting as this Velcro will stay with the machine when you remove the enclosure for the summer riding season. Be the fussy SOB that I am, I did trim the Velcro to match the contours of the body and fender so it would have a better appearance when the enclosure was removed. These plastic body panels are difficult to get anything to stick to very well so this is where the goop comes into play. I did use it on all the Velcro attachments on roll bars and body panels as I only wanted to do this once. You will also have to add Velcro to the rocker panel for the door bottom, I choose to sand with 120 grit all the plastic areas to be glued and cleaned with alcohol to be sure of a good bond. Because my windshield was a home job of course all the mounts were right where the Velcro was needed for the doors, so I had to make mods to the mounting clamp areas so many extra holes in the windshield were needed. I just filled the extra holes with SS screws for appearance, but it now looks like my windshield is built like fort knox! Oh well at least it looks good...Once all the glue was dry some carefull fitting and adjustment was needed to get everything aligned. the zipper was a little sticky so some silicone zipper lube seemed to make things smoother. Getting used to going thru a zippered door takes a little getting used to but not difficult, the loss of cold air blasting your body makes it well worth it. I will be adding a small heater but that is a story for another day. After all was installed and adjusted including the many mods to the windshield and rear view mirrors we were ready for a road trip. I did notice some areas where cold air came blasting in but nothing with the enclosure. It seems that the area around the tilt steering column allows a lot of cold air in so some trimmed pieces of black closed cell foam stuffed into these areas shut off the cold blast and are easily removed when it is time to remove the enclosure. The hard part is the install, you need to be above 60 for the glue to set properly, it takes 24hrs before you can use the Velcro strips you glued on and with fitting everything I had about three days total. When it comes time to remove it, the roof will need to be removed (4 bolts) then the windshield will need to be loosened to remove the Velcro strips on the roll bars ( just loosen not remove) and the rest is just pulling Velcro, starting with doors first then the back panel. The rest of the Velcro that was glued on stays with the machine forever. After a 40 mph road trip the enclosure held up with no issues, nothing came loose, nothing flapped in the wind, it did everything it was supposed to do. Appears to be a quality product, nicely stitched, professionally made and designed at a fair price in todays market. The top gun material used should last for many many years with proper care and the stuff is tough, hard to rip or tear. Also very light in weight as some of the expensive hard enclosures can weigh up to a few hundred pounds! I have comfort knowing I will be much warmer this winter while plowing, so....COME ON SNOW !!
