What sizes are the bottles? Thanks.

Hi the package I got had one cleaner and one fabric guard bottle in the one box as a kit. each bottle was 16 oz. the box had stock # 30520 on it. I also got a 32 oz. bottle as an extra for future use separately of the fabric guard. But the kit bottles were 16 oz. each.

Hello, any alternative successful methods to apply the protectant vs spraying ?

The only way I could see applying the protectant is to maybe soak a clean sponge with it and spread it around the top. However, I can’t say how well this method would work, as I have not tried it. RaggTop brand soft top protectant comes in a spray can. You might try that one. I feel that it is easier to apply and lasts longer. Always start with a clean, dry top.

can you keep cleaning the top with the 303 cleaner after you apply the sealant or will it remove the sealant

Yes. You can always use the 303 Cleaner -even if the surface has already been treated. Hope this helps!

how many ounces are the bottles. and is this product as good as the rag top brand

I'm not sure on the size. I think it was 12oz. As far as a rag top comparison. I can't help either. I used the 303 on my 2006 corvette 2 summers ago. When I put it away for winter the top was as good as the day after I used the 303. Personally, if I have a need for a fabric guard product again I will go back for more 303. Other than needing to use the cleaner in the kit to also clean any over spray from applying it. It has more than met my expectations. Hope this helped.

Amazing product

Just used this on a blue soft top. It’s restored the colour vibrancy as well as making it excellent at repelling water. Recommend the 303 brush for cleaning the roof as well.
