Hiding the mfd date and the expiry details
The manufacturing date and expiry date are hidden under the bar code sticker. This is an offense.

Expensive, but well worth the price.
Purchased the small can amount (8 oz, 1/2 Pint). Begrudged the price $50 plus for this amount, however I needed this specific primer for an RV Slide out Wiper Replacement on the top portion of slide. Removed the original wipers which were beginning to "rubber rot" and decay from sunlight exposure. Lowest price I could find for this primer was three small towelettes for $20 and 7 days delivery with possible import fees from a USA seller. I think it said possible 2ml per towelette. My experience with towelettes is that most times they are dry out before even opening. There were numerous resellers from China, selling small vial bottle containers, also with long shipping times. In my own opinion, this is the primer that works, old wipers were somewhat hard to remove, but they were probably put on with this primer. Seals themselves had the 3M red tape mounted on back. To get them to stick really well use this primer. Also make sure you get your surfaced prepped well. I used a Whizzy Wheel (sold on Amazon.ca) attached to drill to remove the old rubber wiper residue. 8 feet by 1/2 inch surface in less than 5-7 minutes. Cleaned surface with 50% rubbing alcohol and dried in less minute. Applied primer with a cotton make up pad that the wife let me have for free. Waited 20 minutes to make sure primer was dry from heat of sunlight. 3-5 minutes is probably all that is needed, as it dries quickly. Coating about 1ml, very lightly and one wipe across 8 feet. When applying new RV Wiper seal, remove red mounting tape slowly in about 1ft unwinds. Press and seal using the guide on back of seal until finished mounting. Awesome primer. Wiper replacement finished, at least on top of this slide for another 5-7 years. I will do an update then to tell you how hard it is to remove. 42 feet of RV, Four large Slide-outs, probably 160 feet of wipers to replace in the next year. This is the primer to buy, also Amazon.ca had this small can to me in 24 hours with Prime delivery. Awesome.

Works great
Can’t say enough about the primer. Followed the directions of 3M’s site and it worked perfectly. I used it to prepare the rubber roof of my RV prior to applying 3M VHB tape to mount unistrut to the roof without drilling any holes.
