Tank sealing

Trying to limit the posibility of tank particles wrecking my rb. Unfortuatley the tank has just been resprayed so have to be careful when treating. Can you use petseal straight into a drained tank or do you have to do anything else prior to application? When i had it out last time i shingled it and then flushed it with petrol through a muslin cloth till no bits came out then stuck it back in the scoot. Did notice quite a few bits on the filter when i took it off...

Also how do you know that you coated the whole of the inside and not missed any bits?
While im at it are there any inline fuel filters that actually do there job while not slowing down fuel flow?
I think thats about it.....

I have heard bad stories about Petseal breaking up and causing more problems than it should stop... but much of that could be down to poor application...
The tank needs to be completely dry before you start. Pour the stuff in, block the holes appropriately and then turn the tank over and over, so that the liquid goes into all corners. then make sure it is completely dry before putting petrol in again.
I used some sealant from Frost, had no problems in 9000 miles of use.
a company called Tank Care products is another option.

I used that sticky red goo (I can't find the link but someone will oblige I'm sure). They say its flexible and it gets favourable comments on here but when I used it, it turned the fuel into paint stripper and when I stripped the top end down, the piston was covered in sticky goo. (Yes I did leave it a couple of days to dry)

Kreem and Red-Kote work if you use them properly. They are usually 3-part systems. And you first must degrease it, some dishwashing soap, hot water, and a few nuts and bolts will loosen a lot of the rust and grease stuck in there. Then continue to wash it out with warm water.
The first part is an acid, usually phosphoric acid. The second step is the MEK (Methyl Ethyl Ketone) which rids the tank of moisture. The third step is the coating which contains MEK to keep it fluid. Once the MEK dissipates, the coat will harden (You can also add MEK back to the tank to redissolve the coating). The trick is to slowly and constantly turn the tank so as to create an even coat, drain the remainder for reuse, then let it dry in a well ventilated warm area. They say 24 hours, I say let it sit for a week or so to let it cure fully. The coatings are good because they will also prevent the joint in the middle of Lambretta tanks from leaking.
When people complain about this stuff it is usually because they did not take the time to use it properly. And before you stick the tank back in the bike, fill it up with fuel and let it sit, then see if it leaks or if the coating flakes off inside.

I've used Kreem before and netweasel is right. Its all about being meticulous.

Anyone got a anser to one of sef,s query,s about a inline fillter that wont slow the fuel flow down too much, thinking of fitting one to mine, cheers.

I just went to halfords and had a rummage through their stock until I found one about the right size. It worked fine and trapped loads of crap. Not sure if the flow rate would be high enough for an RB or TS1 though.

Sydducket..From what Ben at Rayspeed said if I remember right ..and /i do .if you've stuck an inline filter on your RB you will cause fuel starvation on a high rev thrash...I would prefer to use one but don't fancy the consequences,as for the tank seal issue , I sat my new stainless tank half full of fuel in the garden for a week or so rotating it..in went pink 2 stroke out came grey liquid with bits in. Pressure washed the interior loads ...dried over days..wife's hairdyer..oops. Petsealed it and it dried over a week or so. 1600 miles no issue. However my mate petsealed a stainless and the stuff reacted so badly that it became too hot to handle resulting in an uneven coating that either came away or did the s**t to the blanket trick. I bought the tank off him for my Imola. Pressure washed interior then got some petseal remover (tank care). Once cleaned and dry I used 'tank care products' tank sealer which seems to have done the trick too. I'd like to think that the gauze off a camlam type fast flow tap should stop the rest if you pay attention when fueling and/or messing with scoot...Peter
