Dual seat

[Guest]

I have a seat base in poor rusty condition, but the top cover of the seat is in good condition with no tears.
Has anyone ever fibre glassed the underside of the seat to make stronger.
is this do able?.

The only problem I see with just "undercoating? with fiberglass is that you will be adding thickness between the frame and the seat contact points. Now there is some slop in the seat to frame fit on these old guys but you could potential make it so it doesn't fit under the locking points at the front or the back.

If the seat cover is good and its not a foam blown seat I think it might be better to do it on the inside of the seat pan.

Didnt think of that, Thankyou very much will look at inside of seat pan 👌

I have done a bunch of work in fiberglass in my old life as an exhibits person. If you can build up the inside with some fair overlap and let it cure well you should never have to worry about the pan again. I would just then make sure to get a good coat of enamel on the metal underside.

Thanks for the advise very very much appreciated 👌

That's an excellent point! But, if you must work on the outside, you might try exploring these contact points with corrugated cardboard to see where the places are...a corrogated cardboard comes near to duplicating a minimal fibreglass thickness..? so maybe try two thicknesses as well to see where you can build up some strength....it's just an idea that might help avoid screwing up at the "crush points"that Boriqua pointed out. It might also prove you MUST work from the inside of the pan...

Very good idea Thankyou, I will try that and hopefully get a fibreglass coat both sides of the pan.
i,m going to pop rivet a replacement 25mm angle around the outside of the pan ( to cover the rotten part) as well so I can fit the spike strip as advertised by p and k classic bikes
