Hello Beezer, the above post puts the job in perspective,ie.sealing the tank,and doing it properly
was of some concern to me,and I had to give it a lot of thought. I had checked the tank on my velo.and noticed a deterioration on the inside caused by the onset of rust which shook me a little bit. I knew I had to do something about it,but same as you I was undecided because there is quite a diverse opinion about different products and methods.I checked as much info. as I could on various forums etc.,and decided to try the POR15 sealer.A case of suck it and see.
The tank I had to do is a real beauty,with a very good finish to the paint work,which,if I got it wrong would cost me a packet to get sorted,and I had no real knowledge of what damage the POR15 would do if I got any on the tank paintwork,so the sealing was a really important issue.
I had looked at several of the bung type methods for the petrol tap holes,but I still wasnt happy,
I had an idea, I had a few old and useless petrol taps,so I took the filters off a pair,and then filled the insides with Araldite to block them up,and then screwed them into the tank in the usual way,
they worked a treat,they were also very handy for a bit of grip whilst shaking the tank.
The next job was the petrol cap,bearing in mind this has to be opened and closed several times
during the job. Thoughts of having to sell the wifes bits of jewellery to have the tank painted again crossed my mind as to achieve this and not ruin the paint was not going to be easy. Actually
it was. I finished up using some layers of sandwich bags,which I cut into squares which amply
covered the filler hole,I put several layers over the hole one at a time until I could close the filler
cap and feel it clip in to place,without undue pressure.Mine is the lift up and press down type.
I tried the idea several times with water in the tank and it worked fine with no leaks.[ for me.]
The POR15 Marine clean is the thinnest of the kit ingredients,mostly water,the sealer itself is a
little like thin cream and is easier to control.
During the job with the sealer itself,I also took the petrol taps out between coats,and cleaned and replaced them. They worked perfectly, no problems whatsoever.
By the way if any one wants to use them be my guest.
I could blather on a bit more about the actual job,but you are not sure which way you are going to go.There is one thing,if you are going to paint your tank later, it wont be as scary.
Keep us posted on what you do.
Cheers,Mel.
Heres a couple of pictures of the tank. I hope. Taken during the job.
