Squirt Tyre Sealant with Beadblock
From: bikebox.com.au
RRP: $55.00 for 1000mL
Time to seal a 3mm hole: 0:58
Pressure lost: 1.2psi
Time to seal a 6mm hole: 4:18 – Dynaplug used as pressure was too low
Pressure lost: 10.9psi
AMB’s notes: Squirt’s tubeless sealant uses the Beadblock additive, which helps it seal smaller punctures faster, and seal bigger holes. To prevent the extra bits from settling in the base of the bottle and being useless, Squirt provide a separate container, and you add it with the sealant. 120mL was required for this test, so each setup is about $6.60 based on the 1L bottle. The results speak
for themselves – to a point. This was a very fast repair on a 3mm hole, but the pressure loss was too much to keep riding for the 6mm cut, and a plug was used. The tyre did reinflate after this, but when opened up to check the sealant, there was barely
a trickle left, with a lot of dried Beadblock on the casing. Despite 120mL in there, a lot may have been needed for the first puncture, and then the majority lost after the second. Still, it worked the fastest
of all, and probably a match with Orange Seal and Stan’s considering margins for error in timing. This is a good value option, but one best partnered with a plug kit when it sounds like you've got a big hole.

Maxima Tubeless Sealant
From: lustyindustries.com
RRP: $39.99 for 473mL
Time to seal a 3mm hole: 3:25 – plugged due to pressure loss.
Pressure lost: 13psi
Time to seal a 6mm hole: FAIL – under 30 seconds to flat
Pressure lost: Complete
AMB’s notes: Maxima Tubeless Sealant needed 120mL of sealant for the 2.4” test tyre, which puts it at about $10 per wheel. The test results weren’t good, especially with Maxima’s claims of upto 6 months product life. The 3mm cut lost enough pressure to need a plug to seal it, and th 6mm cut ejected so much air so quickly I couldn't even slow down and get a plug to it in time.
I reinflated the tyre (with two plugs) the next day with fresh sealant and it sealed up. I repeated the test, with the fresh sealant, and the 3mm hole sealed in 1:04 with 2psi lost. After reinflation to 22psi, the 6mm cut dropped to 10psi in 3 minutes and would need a plug to seal completely, as at that pressure you’re not riding anymore. This
is a good sealant and it works fast when fresh, but I think it may go off in Australian heat faster than Maxima expect. This procedure is far from conclusive on that front.
