I have scrim and some large blue microfibre glass cloths,fine weave,.13 dernier,320gsm,80x 62cm, from paragon microfibre.i`m down to only 2 left of the microfibre so need to order more and just had a look at paragon`s site and they have some new types out,the current ones i have are as good as scrim and feel as long lasting and the descriptions on the site suggest they have something better now(possibly).Anyway i was recommended Paragon Microfibre Ltd by this forum and am happy to vouch for them as well,easy to order on the site as well and certainly worth a look.
