easy to apply! but havent try out on rain yet to comment..
although i think its best if you can print/write the instruction to be sent together with the package..i emailed the instruction you gave me thru pm and on the way i was having doubts but already half way messy hands/gloves..i had to touch my phone to check the instructions..
i think the one selling windscreen for roadtax print out and thank god for it!
just my 2cents..
